Revert "mediaextractor: ignore platform's profiler assist signal"
This reverts commit 0c3505bfb63906067c42eb4e4f03fc2cf565ba14.
Reason for revert: aosp/1242758 protects against sigsys-based seccomp
crashes from within the profiling signal handler. This should make the
mediaextractor-specific disabling of the profiling handler unnecessary.
Test: sent profiling signal to mediaextractor, observed logging
that confirmed that the sendmsg() violation was recovered-from.
