[testsuite] fix gcc.target/powerpc/pr47197.c

[Janis Johnson]

Test gcc.target/powerpc/pr47197.c passes "-maltivec" without first
checking that the option is allowed on the target, which is not the case
for powerpc-eabispe.  This obvious patch fixes the problem by requiring
powerpc_altivec_ok; checked in on mainline and the 4.8 branch.
