[compiler-rt][profile][AIX] pass extra link opts for test

This is a follow up to D118101, that added bexpfull to the test on instrprof-get-filename-merge-mode.c AIX, in order to get the
necessary symbols exported. But unfortunately the extra dependent symbols this exports actually cause segfaults, which is why
this isn't really recommended in the first place, so just use an actual export list.
