perf tools: Version incorrect with some versions of grep

commit 58d406ed6a5f1ca4bc1dba5390b718c67847fa5f upstream.

Some versions of grep don't treat '\s' properly. When building perf on such
systems and using a kernel tarball the perf version is unable to be determined
from the main kernel Makefile and the user is left with a version of '..'.
Replacing the use of '\s' with '[[:space:]]', which should work in all grep
versions, gives a usable version number.
