Log:
[libprofile] Make this test express intent a bit better.

This also makes it work on PS4 a bit better.
For running the libprofile tests on PS4, we are sneaking environment
variables through on the command line, so the extra argument for
LLVM_PROFILE_FILE was messing up the simple `argc < 2` check.
