testsuite: Disable vector-compare-1.C for arm targets [PR121752]

So arm is a bit special, non_strict_align is sometimes true but
it does not represent the true value of STRICT_ALIGN inside the compiler,
so this testcase fails. This disables the testcase for arm targets where
STRICT_ALIGN is always true even when there is unaligned loads.

Pushed as obvious after testing on x86_64 and arm-eabi (with -march=armv7) to make
sure the testcase no longer run on arm.
