[gentoo-musl] Adding ebuild for a current stable version of net-misc/chrony

Hello everyone!

The attached patch will add ebuild for a current stable version of
net-misc/chrony (adopted for musl, of course). I've tested it on a couple
of arm64 installations and it works fine.

So, maybe you add it to your overlay? Maybe i need to change something
in this patch? It is first my attempt to create ebuild)

With best regards,
Pavel Aliev
