tools/perf/build: Fix non-canonical directory names in O=
This was a long-standing bug, relative pathnames like O=dir did not fully
work in the build system:
$ make O=localdir clean
SUBDIR Documentation
../../scripts/Makefile.include:3: *** O=localdir does not exist. Stop.
make[1]: *** [clean] Error 2
make: *** [clean] Error 2
Fix this by canonizing the directory before passing it to Makefile.perf.
