testsuite: Make pr104992.c irrelated to target vector feature [PR113418]

The vect_int_mod target selector is evaluated with the options in
DEFAULT_VECTCFLAGS in effect, but these options are not automatically
passed to tests out of the vect directories.  So this test fails on
targets where integer vector modulo operation is supported but requiring
an option to enable, for example LoongArch.

In this test case, the only expected optimization not happened in
original is in corge because it needs forward propogation.  So we can
scan the forwprop2 dump (where the vector operation is not expanded to
scalars yet) instead of optimized, then we don't need to consider
vect_int_mod or not.

gcc/testsuite/ChangeLog:

	PR testsuite/113418
	* gcc.dg/pr104992.c (dg-options): Use -fdump-tree-forwprop2
	instead of -fdump-tree-optimized.
	(dg-final): Scan forwprop2 dump instead of optimized, and remove
	the use of vect_int_mod.
	* lib/target-supports.exp (check_effective_target_vect_int_mod):
	Remove because it's not used anymore.
