aarch64: testsuite: disable PIE for fuse_adrp_add_1.c [PR70150]

In PIE, symbol "fixed_regs" is addressed via GOT.  It will break the
scan-assembler pattern and cause test failure with --enable-default-pie.

gcc/testsuite/ChangeLog:

	PR testsuite/70150
	* gcc.target/aarch64/fuse_adrp_add_1.c (dg-options): Add
	-fno-pie.
