[pushed 2/3] [gdb/testsuite] Use have_gnu_debuglink in two more test-cases

[Tom de Vries <tdevries@suse.de>]

When running test-cases gdb.debuginfod/crc_mismatch.exp and
gdb.debuginfod/solib-with-soname.exp with target board cc-with-gnu-debuglink,
we get:
...
UNSUPPORTED: gdb.debuginfod/crc_mismatch.exp: \
  cannot produce separate debug info files
UNSUPPORTED: gdb.debuginfod/solib-with-soname.exp: \
  debug information has been split to a separate file
...

Use proc have_gnu_debuglink to get the more precise:
...
UNSUPPORTED: gdb.debuginfod/crc_mismatch.exp: \
  require failed: !have_gnu_debuglink $binfile
UNSUPPORTED: gdb.debuginfod/solib-with-soname.exp: \
  require failed: !have_gnu_debuglink $binfile
...
