[PATCH 3/5] perf tests: Add DESTDIR=TMP_DEST tests/make variable

[Jiri Olsa <jolsa@redhat.com>]

Adding TMP_DEST tests/make variable to provide the
DESTDIR directory for installation tests.

Adding this to existing test targets, since DESTDIR
variable 'should not' affect other than install*
targets. We can always separate this if there's a
need for DESTDIR-free build test.
