[PATCH] TestCommon: older strace does not have --version

[Konstantin Ryabitsev <konstantin@linuxfoundation.org>]

The tests will check for strace >= 4.16, but version 4.24 that I have
does not accept --version, only -V. This works for both older and newer
strace, so switch to using "strace -V" for the check.
