fix: update /bin/bash to /usr/bin/bash

Now /bin is a symlink to /usr/bin, which means that trying to look at
the service with eg.

    systemctl --user status clipper.service

errors out with:

    $HOME/.config/systemd/user/clipper.service:10: Neither a valid executable name nor an absolute path: ExecStart=/bin/bash

I initially created this patch by editing the service.patch file
directly with the new path, tweaking the `pkgrel` version number in the
PKGBUILD (note that there's nothing interesting in the Clipper repo
since the previously commit -- only doc updates -- so the `pkgver` stays
the same), and then running:

    updpkgsums # from pacman-contrib, IIRC
    makepkg --printsrcinfo > .SRCINFO

but then I thought better of it and decided to do the Git version update
(to `pkgver`) as well:

    makepkg --noconfirm -s -c
    makepkg --printsrcinfo > .SRCINFO
