testsuite: [arm] Include arm_acle.h in related effective targets

Since arm_acle.h includes stdint.h, its use requires the presence of
the right gnu/stub-*.h, so make sure to include arm_acle.h when
checking the effective targets that generally imply that the testcase
will include it: arm_dsp, arm_crc, arm_coproc[1-4]

This makes several tests unsupported rather than fail.
