elf: Fix tests that rely on ld.so.cache for cross-compiling
For configurations with cross-compiling equal to 'maybe' or 'no', ldconfig will not run and thus the ld.so.cache will not be created on the container testroot.pristine. This lead to failures on both tst-glibc-hwcaps-prepend-cache and tst-ldconfig-ld_so_conf-update on environments where the same compiler can be used to build different ABIs (powerpc and x86 for instance). This patch addas a new test-container hook, ldconfig.run, that triggers a ldconfig execution prior the test execution. Checked on x86_64-linux-gnu and i686-linux-gnu.
