dynamic libc: ignore ART profiling signal by default.

These solves the issue that targetting non-profilable apps crashed them.
There is still a race condition between starting the app and the SIG_IGN
being installed, but that will be fixed in follow-ups.

This also does not cover programs that statically link libc, but those are
rare.

This might be reverted if we find a more general solution to
b/151835887.
