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
