docker: Bump default LLVM used for tests to 11
This is another prep commit for running docker tests on both 18.04 and
20.04 versions of ubuntu. 20.04 doesn't have some LLVM 8 libs that the
docker build expects, so bump to 11.
Bumping to 11 causes test_disassembler to fail because it expects a map
w/ a certain format with FD 3, and the LLVM bump causes the map to be
FD 4. The purpose of the test is to ensure that the format of the
diassembled map is correct, not that it has a specific FD, so make some
small changes to the test so that it doesn't care what the FD number is.

docker + tests: Run tests using python3, refactor Dockerfile
In #3707, I added ubuntu-20.04 to the list of OS's bcc-test uses to run
tests. I expected that this would result in the tests running on both
18.04 and 20.04. Unfortunately this change was effectively a no-op as
the tests are run in a Docker container and the os field in bcc-test.yml
dictates the type/version of the _host_ OS, not the container's OS.
So it's not necessary to run on both, just run on 20.04. It will be
necessary to modify Dockerfile.test to use both 18.04 and 20.04. To
prepare for this, move all python tests to use python3 interpreter, as
20.04 doesn't have python2 pip readily available.
Also, refactor Dockerfile.tests a bit so that it's possible to provide
ubuntu version and shortname as build input.
This commit does not result in the docker test container working/running
both 18.04 and 20.04, rather lays groundwork for future commits to do
so.

tools: tcptop: Get command name from BPF code. (#3760)
Before this commit, command name was taken from PID using /proc/PID/comm.
But this method was not reliable as it does not work all the time.
So, this commit takes command name from BPF code using bpf_get_current_comm()
helper like it is done for biotop.

Implement bashreadline with libbpf.
Bashreadline will print user inputs, returning from readline, of every
instance of bash shell. Readline is in bash itself, linked
statically, for some devices, while others may link to libreadline.so.
This implementation finds the symbol in bash if possible. Or, it tries
to find libreadline.so using ldd if the symbol is not in bash.

test_tools_smoke.py: Helpful fail msg for timeout cmd's ret code
The test_tools_smoke script uses bash's 'timeout' command to run bcc
tools for a limited duration, sending a HUP after 5s and a KILL 5s after
that. Currently, when a tool exits in an unexpected way (e.g. we
expected a HUP to be required, but the tool required a KILL), the test
failure message isn't very descriptive.
This adds a more human-readable explanation of what's going on.
