perf synthetic-events: Fix bounds and union member access in mmap2 build_id synthesis
Modify bounds and union member access in mmap2 build_id synthesis. Bound
max_filename_len against the minimum of filename array capacity and the
outer union stack layout minus sample ID trailers. This prevents both
-E2BIG overruns and _FORTIFY_SOURCE array bounds aborts on strlcpy even
if the enclosing union expands.
