Wainer dos Santos Moschetta fb82116f24 Update string tests to use the support test driver.
Replaced all imports of test-skeleton.c with support/test-driver.c.

In some cases it was needed to adjust do_test to return int
instead of static int since that is the method's signature expected by
test-driver.c.

Checked on x86_64.

	* string/test-string.h (TEST_FUNCTION): Use test_main instead of
	test_main ().
	(CMDLINE_PROCESS): Use function instead of defined macro.
	* debug/test-strcpy_chk.c: Import support/test-driver.c and also
	<suppport/support.h> to use set_fortify_handler().
	* string/bug-envz1.c: Import support/test-driver.c instead of
	test-skeleton.c.
	* string/bug-strcoll2.c: Likewise.
	* string/bug-strtok1.c: Likewise.
