Currently the SIMD register sampling is supported, but the corresponding
handling is missed in aslr_tool__process_sample(). This can break parsing
of the sample record.
Add the missing SIMD register handling in aslr_tool__process_sample().

These two patches fix Sashiko reported defects for the patchset:

Sashiko complains "the perf tool can be compiled with musl libc, which
enforces strict POSIX namespace separation and does not implicitly
include headers. Relying on implicit header inclusion can cause build
failures under musl."
Include the required headers explicitly to avoid such failures.

Kindly ping ...
@Arnaldo, @Namhyung, @Ian, not sure if you have bandwidth to review this
small patchset which fixes the Sashiko found minor issues for the "Perf
tools: Support eGPRs/SSP/SIMD registers sampling" patchset?
If possible, it's better to be queued in this cycle, then we don't need
extra backporting. Thanks.

nit: at the end of the function you could #undef CHECK_SIMD to make it
more explicit that the macro only makes sense within the function.

Oh, another nit: there's a typo in the commit message subject: s/alsr/aslr/g.
