oprofile: Add PTEST regression testing to oprofile

The commit changes the oe-core oprofile recipe by adding the PTEST
interface, implementing do_compile_ptest() and do_install_ptest().

The install routine adds several files that only the regression tests
require. Also, a patch is necessary to inhibit executing the tests on
the build host and to point to the correct target directory for the
libutil++ test 'file-manip-tests'.

That test requires the recipe to set SRCDIR in the build environment
instead of determining the value from build-time host paths as for a
self-hosted build.

+Prevent running check tests on host if cross compiling
+
+This patch enables running the 'make check' tests on the target
+in a cross-compiled environment. If not cross-compiling, then 'make
+ check' builds and executes the tests; no change from this patch.
+In a cross-compiling environment, the make variable CROSS_COMPILE is
+set which bypasses assiging tests to the makekfile variable TESTS.
+Since TESTS is empty, the 'make check' process never tries to run the
+tests on the hosts.  On the target, the tests must be run manually.
+
+Also, in the libutil++ tests, a makefile variable SRCDIR is passed into
+the compilation phase, pointing to the runtime location of the test
+'file-manip-tests'.  The mechanism used for a host test, based on
+'topdir' doesn't work.  Instead, if CROSS_COMPILE is set, the
+makefile takes the path of SRCDIR from the build environment and not
+from an expression based on the host path 'topdir'.
