[fix] Several issues with the provided `PKGBUILD`.

[dreirund]

The current PKGBUILD in this repository has some issues:

• You take the latest checkout from git. $pkgver must be strongly monotoneously increasing with every git commit. Use the pkgver() function for it. And I suggest that you put your main version (0.2.2) somewhere where it can be parsed from the sources or/ and git repository, e.g. a version.h (or rust-alike file) which is used by the compilation process to bake in the version number into the binary, and which can be read out by pkgver()
• Please add provides=("pineflash=${pkgver}"), conflicts=("pineflash").
• git needs to be added to makedepends.
• gtk3 needs to be added as dependency.
• If possible, make rust download all it's dependencies within $srcdir, and make that download already happen in prepare(), so that no internet connection is needed in build() or package().
• Move compilation to build().
• Copy, not move, the files to be installed in place. Use the install command preferably.
• GPLv2 is not a valid license under /usr/share/licenses/common/. Use GPL2.
• You build a binary. So, arch=('any') is wrong. You need to list all supported processor architectures explicitly.

A PKGBUILD which adresses most of this issues can be found → here.

Regards!, and thanks for the software.

Thanks for pointing out the issues, a bit later ill take a look at the one you've added to the aur and put it into the git repo after changing anything that needs changing (a quick view shows the arch is missing stuff like aarch64 but ill get around to changing that later in the day) Thanks again for the proposed changes and putting this in the aur.

Took me a while but i finally got around to it, thanks for the proposed changes ive added em in. Its basically a copy of your aur package but with the pkgver() just getting the version from the cargo.toml.
