The firmware_handler.HandleAbort and subcontext.RecoverAfterAbort
tests intentionally abort in the child process to ensure that
ueventd/init can recover if their child processes die. This generates
a tombstone which causes confusion. This change resets SIGABRT to
SIG_DFL right before the abort(), so that the child processes will
exit normally without generating a tombstone or writing a crash to
logcat.

Bug: 175383788
Test: run the above tests and verify no stack traces are printed to
logcat and no tombstones are generated.

Userspace may want to load a different firmware than the one that the
kernel requests in some cases, therefore this change adds the ability
to ueventd to run an external handler that will determine the name of
the file that should actually be loaded.
