testsuite: Fix some endianness bugs in p9 runnable tests.

This patch fixes some bugs in the powerpc testsuite for runnable tests
whose expected values were endian dependent.

gcc/testsuite/ChangeLog:

2020-10-15  David Edelsohn  <dje.gcc@gmail.com>

	* gcc.target/powerpc/builtins-1-p9-runnable.c: Adjust for big endian.
	* gcc.target/powerpc/builtins-7-p9-runnable.c: Same.
