RFC: fix python-selftest.exp failure (Was: new FAIL python-selftest.exp in gdbserver mode [Re: [PATCH 18/28] check gdb_python_initialized everywhere])

[Tom Tromey <tromey@redhat.com>]

Jan> in gdbserver mode:
Jan> Running gdb/testsuite/gdb.gdb/python-selftest.exp ...
Jan> PASS: gdb.gdb/python-selftest.exp: breakpoint in captured_command_loop
Jan> ERROR: tcl error sourcing gdb/testsuite/gdb.gdb/python-selftest.exp.
Jan> ERROR: gdbserver does not support run -nw -nx -data-directory /unsafegdb/testsuite.unix.-m64/../data-directory without extended-remote
[...]

python-selftest.exp fails with an error when using the
native-gdbserver.exp board.

The bug is that the selftest code doesn't work in this situation.  It
never has.

This patch fixes the problem by pushing the needed check into
do_self_tests.  This helps prevent the problem in the future.

	* lib/selftest-support.exp (do_self_tests): Reject remote or
	non-native targets.
	* gdb.gdb/complaints.exp: Remove check.
	* gdb.gdb/observer.exp: Remove check.
	* gdb.gdb/xfullpath.exp: Remove check.
	* gdb.gdb/complaints.exp: Remove check.
