[gdb/testsuite] Handle internal-error in gdb_unload

Browse Source 
When reverting commit 5a20fadc84 and using gdb_unload instead of runto "bar"
to trigger the internal-error in test-case
gdb.dwarf2/locexpr-data-member-location.exp, we run into:
...
ERROR: couldn't unload file in $gdb (timeout).
...
and the test-case takes about 1 minute.

Fix this by handling internal-error in gdb_unload, such that we have:
...
ERROR: Couldn't unload file in $gdb (GDB internal error).
ERROR: Could not resync from internal error (eof)
...
within 2 seconds.

Tested on x86_64-linux.
