[PATCH 08/11] perf tests: Add DESTDIR=TMP_DEST tests/make variable

[Arnaldo Carvalho de Melo <acme@infradead.org>]

From: 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.
