llkd: Skip apexd for process checks
apexd is a sensitive daemon, and the ability to ptrace this domain is
restricted by SELinux policy. apexd spawns a binder thread which
makes matching difficult, as we would instead need to use
/system/bin/apexd as the blacklist key.
Change llkd to also check for a match on the basename of the
executable path. This will solve a gotcha expectation when creating
a blacklist key.
Without this change, llkd continues to generate SELinux denials of
type=1400 audit(0.0:1764): avc: denied { ptrace } for comm="llkd" scontext=u:r:llkd:s0 tcontext=u:r:apexd:s0 tclass=process permissive=0
Commit 5390b9add4e567eeeeeabc3d39d588c21cb5d543 was originally intended
to fix these denials, but it seems to have had no effect and the denials
are still being generated. This change will fix it.
Test: none
