Subject: [PATCH] Filter out SPE records with irrelevant PIDs

975aadd929cbe4995773e3676df1319f95d10916 added support for single
binary profiles to SPE-based AFDO profile generation, but it broke
support for multi-binary profiles by removing PID-based filtering.

Re-add the line that filters out non-mapped PIDs, as even single-
binary profiles should include mmap entries for the profiled binary.
