arm, mve: Pass -std=c99 to dlstp-loop-form.c to avoid new warning

This fixes a testism introduced by the warning produced with the -std=c23
default.  The testcase is a reduced piece of code meant to trigger an ICE, so
there's little value in trying to change the code itself.

gcc/testsuite/ChangeLog:

	* gcc.target/arm/mve/dlstp-loop-form.c: Add -std=c99 to avoid warning
	message.
