pkg: phosh: gnome-clocks-mobile: make alarms wake from deep sleep

[kclisp]

Adds a patch, ported from https://git.alpinelinux.org/aports/tree/community/gnome-clocks/0001-waked-implementation.patch

Adds a PKGBUILD for waked

Fixes #100

This is my first code contribution to this project and first PKGBUILD, so I'd like a bit of guidance:

1. For waked to be enabled with systemd, you can run (according to upstream):

systemctl enable waked
systemctl start waked

(which should be the same as systemctl enable --now waked). Is there anything I can do with this info?

2. waked requires sdbus-cpp, which is available on the AUR (https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=sdbus-cpp), but it doesn't list aarch64 in its arch. I added it manually, and it seems to work. The PKGBUILD for sdbus-cpp also makes code gen and docs, which seems unnecessary to me. What do you suggest I do here? Make a PKGBUILD under phosh, or see if the maintainer can change it?

Other suggestions and comments are welcome.
