perf tools: Handle --version string generation on machines without git
If git is installed we'll have a 'perf --version' output of this form: $ make -j8 -C tools/perf/ O=/home/acme/git/build/perf install $ perf --version perf version 3.7.rc3.g3afad6 Now on a machine without git installed: $ mv /home/acme/bin/git /home/acme/bin/git.OFF $ make -j8 -C tools/perf/ O=/home/acme/git/build/perf install $ perf --version perf version 3.7.0-rc2 That is, no error message due to git not being installed will appear on the screen and instead the version string in the top level Makefile will be used.
