[PATCH v2 09/17] update checkpoint test

[Tom Tromey <tromey@redhat.com>]

This fixes the "checkpoint" test to use the standard output directory.
This makes the test be parallel-safe.

	* gdb.base/checkpoint.c (main): Use PI_TXT and COPY1_TXT
	defines.
	* gdb.base/checkpoint.exp: Define PI_TXT and COPY1_TXT during
	compilation.  Use prepare_for_testing, standard_output_file.
