gold: Use asm for GCC 9 and older in PR gold/31830 tests

Since GCC 9 and older fail to compile PR gold/31830 tests:

$ gcc -S testsuite/ver_test_pr31830_b.c -o /tmp/x.s
testsuite/ver_test_pr31830_b.c:3:1: warning: ‘__symver__’ attribute directive ignored [-Wattributes]
 void __collector_foo_2_2(void) {}
 ^~~~

use asm statement, instead of symver attribute, for GCC 9 and older.

	PR gold/31830
	* testsuite/ver_test_pr31830_b.c (__collector_foo_2_2): Use asm
	statement, instead of symver attribute, for GCC 9 and older.
	symver attribute with __asm__.
	* testsuite/ver_test_pr31830_lto.c (__collector_foo_2_2): Likewise.
