sys-libs/glibc: introduce USE=+crypt

Today libcrypt.so.1 is provided by glibc. Eventually glibc will
stop providing it in favoud of external providers like libcrypt.

USE=crypt exposes a knob to disable libcrypt.so.1 installation.
Use at your own risk. There currently is no replacement yet in
Gentoo.
