[PATCH 2/2] perf: Version String fix, for fallback if not from git

[Thavidu Ranatunga <tharan@au1.ibm.com>]

This gets rid of the default version fallback for Perf and changes it so that it
returns the version of the kernel from it's Makefile (if sources were not from
git, ie. if it was downloaded from a tarball)
