Joshua Peraza c4cc4e6ac9 android: initialize signal dispositions 
Bionic installs signal handlers which request crash
dumps from Android's debuggerd, but there are errors
in how signals which aren't automatically re-raised
are handled on Marshmallow (API 23).

Before requesting a dump, Bionic acquires a lock to
communicate with debuggerd and expecting imminent
death, never releases it.

While handling the dump request, debuggerd allows
the dying process to continue before
ptrace-detaching it. So, when Bionic manually
re-raises a signal, it is intercepted by debuggerd
and the dying process is allowed to live.

Bionic restores SIG_DFL for the signal it's just
handled, but if a different crash signal is later
recieved, Bionic attempts to reacquire the lock to
communicate with debuggerd and blocks forever.

Disable Bionic's signal handlers for these signals
on Marshmallow.
