[GWP-ASan] Fix non-reentrant libc_globals init behaviour.
The WriteProtected mutator for __libc_globals isn't reentrant.
Previously we were calling __libc_globals.mutate() inside of GWP-ASan's
libc initialisation, which is called inside the __libc_globals.mutate().
This causes problems with malloc_debug and other malloc shims, as they
fail to install when GWP-ASan is sampling their processes.

Test: atest bionic
