perf trace: Fix ioctl 'request' beautifier build problems on !(i386 || x86_64) arches
Supporting decoding the ioctl 'request' parameter needs more work to properly support more architectures, the current approach doesn't work on at least powerpc and sparc, as reported by Ben Hutchings in http://lkml.kernel.org/r/1391593985.3003.48.camel@deadeye.wl.decadent.org.uk . Work around that by making it to be ifdefed for the architectures known to work with the current, limited approach, i386 and x86_64 till better code is written.
