Fix 30808 gprofng tests failed

In gprofng testing, we need a tempory gprofng installation to resolve run-time
dependencies on libraries (libgprofng, libopcodes, libbfd, etc).
We set LD_LIBRARY_PATH and GPROFNG_SYSCONFDIR to find our libraries and
configuration file. These variables must be set for all gprofng tests.

Tested on aarch64 and x86_64 with and without --enable-shared and --target=<>.
