perf: Fix unaligned accesses while fetching trace values
Accessing trace values of an 8 size may end up in a segfault
on archs that can't deal with misaligned access, which is the
case for sparc 64. This is because PERF_SAMPLE_RAW are aligned
to 4 and not to 8.
Fix this on the macros that get the values of 8 size.
This fixes segfaults on perf tools in sparc 64.
