perf synthetic-events: Fix bounds, stale state, and misc flags in kernel module synthesis
Clamp long DSO names to mmap/mmap2 filename boundaries accounting for
sample ID headers to prevent buffer overruns in
perf_event__synthesize_modules_maps_cb(). Explicitly clear misc flags and
union padding to prevent stale Build-ID state from leaking between module
synthesis events, and cast event buffer pointers to avoid _FORTIFY_SOURCE
array bounds aborts when zeroing padding trailers.
