Fixed a profdata file size detection on Windows system.

[vvereschaka]

Summary

The space symbols are allowed in the group names on Windows system (as example: Domain Users). In that case the test extracts a wrong field from the output to get a size of the profdata file.

This patch avoids a printing of the group names in the test output and extracts a proper field as a file size.

Sorry I missed the patch. Thanks for fixing the test!

This broke the NetBSD buildbot: http://lab.llvm.org:8014/builders/netbsd-amd64/builds/140/steps/run%20unit%20tests/logs/FAIL%3A%20LLVM%3A%3Ashow-prof-size.test

The -o option is not portable, and does something completely different on NetBSD:

-o      Include the file flags in a long (-l) output.  If no file flags
        are set, “-” is displayed.  (See chflags(1) for a list of
        possible flags and their meanings.)

The same is true for at least FreeBSD and macOS. So this patch breaks more platforms than it fixes.

-o is an unportable extension.

Thanks @mgorny and @krytarowski for letting me know.

Looks like there is no way to make a portable fix using 'ls' tool.
I am going to revert this commit.
