perf tools: Create source symlink in perf object dir

Create a source symlink to the original source in the objdir.

This is similar to what the main kernel build script does.

Committer testing:

  ⬢[acme@toolbox perf-tools-next]$ make O=/tmp/build/$(basename $PWD)/ -C tools/perf install-bin
  <SNIP>
  ⬢[acme@toolbox perf-tools-next]$ ls -la /tmp/build/perf-tools-next/source
  lrwxrwxrwx. 1 acme acme 41 Aug  9 16:26 /tmp/build/perf-tools-next/source -> /home/acme/git/perf-tools-next/tools/perf
  ⬢[acme@toolbox perf-tools-next]$
