perf trace: Fix non-listed archs in the syscalltbl routines 



This fixes a build breakage on 32-bit arm, where the
syscalltbl__id_at_idx() function was missing.

Committer notes:

Generating a proper syscall table from a copy of
arch/arm/tools/syscall.tbl ends up being too big a patch for this rc
stage, I started doing it but while testing noticed some other problems
with using BPF to collect pointer args on arm7 (32-bit) will maybe
continue trying to make it work on the next cycle...

Fixes: 7a2fb561 ("perf trace: Fix iteration of syscall ids in syscalltbl->entries")
