[gdb] Avoid warnings in cooked_{read,write}_test for m68hc11
With --enable-targets=all we have:
...
$ gdb -q -batch -ex "maint selftest"
...
Running selftest regcache::cooked_read_test::m68hc11.
warning: No frame soft register found in the symbol table.
Stack backtrace will not work.
Running selftest regcache::cooked_read_test::m68hc12.
warning: No frame soft register found in the symbol table.
Stack backtrace will not work.
Running selftest regcache::cooked_read_test::m68hc12:HCS12.
warning: No frame soft register found in the symbol table.
Stack backtrace will not work.
...
Likewise for regcache::cooked_write_test.
The warning has no use in the selftest context.
Fix this by skipping the specific selftests.
Tested on x86_64-linux.
