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.
