Linux/ARM: Add execution time of ./tests/runtest.sh
We have to wait for a long time to complete all unit tests on the ARM-based
embedded boards (e.g, Raspberry Pi, Odroid, Chromebook) compared to the
X86-based server environment. So, let's display execution time after finishing
the unit test.
* After PR:
128 minutes and 36 seconds taken to run CoreCLR tests.
ver1:
The existing measured time still includes overlay creation and some
package restoration. So, let's put time_start in front of
if($testDirectories).
