bcc/python: fix attach kprobe/kretprobe using regex

Attach kprobe/kretprobe using regular expression should fail
explicitly if no functions are traceable. Currently we catch
all exceptions and if no functions are available, program
continue with no BPF programs attached. In this commit, change
this behavior to explicitly report error to user.
