handle gdb,noinferiorio in a couple of gdb.gdb/ tests

[Pedro Alves <palves at redhat dot com>]

I'm applying this.

Skip unsupported functionality against extended-remote gdbserver.

Tested on x86_64 Fedora 16.

2012-02-02  Pedro Alves  <palves@redhat.com>

	* gdb.gdb/complaints.exp: Skip if gdb,noinferiorio is set.
	* gdb.gdb/selftest.exp (test_with_self): Handle gdb,noinferiorio.
