refactor(udev): drop hand-rolled ZSA rule, install qmk package instead

The qmk Arch package ships /usr/lib/udev/rules.d/50-qmk.rules covering
all major mech-keyboard vendors including ZSA's VID 3297, with the
same TAG+=uaccess semantics. Prefer that over maintaining our own
rules file.

- meta/base.txt: + qmk
- etc/udev/rules.d/50-zsa.rules: removed
- etc deploy script: drop the udevadm reload (only existed to support
  our custom rule; pacman handles reloads for package-shipped rules).
