[gdb/testsuite] Use expect_build_id_in_core_file a bit more

Recent commit c1950dcc04c ("gdb/testsuite: fix failure from
gdb.python/py-corefile.exp") introduced proc expect_build_id_in_core_file,
which detects the problem that:
...
    ... some versions of the linker didn't place the build-id within the first
    page of an ELF.  As a result, the Linux kernel would not include the
    build-id in the generated core file, ...
...

Use this proc in a few more test-cases, to deal with the same problem.

Tested on x86_64-linux, openSUSE Tumbleweed with ld 2.43.1.
