[WIP] New packages: proton-bridge-1.2.7 and dependency
https://github.com/void-linux/void-packages/pull/22559

Description:
I'm trying to package [proton-bridge](https://github.com/ProtonMail/proton-bridge), but I'm running into some issues with the build process. Here's the relevant output from xbps-src:
```
make: qtdeploy: No such file or directory
make: *** [Makefile:66: cmd/Desktop-Bridge/deploy/linux/proton-bridge-1.2.7-live.1] Error 127
=> ERROR: proton-bridge-1.2.7_1: do_build: '${make_cmd} CC="$CC" CXX="$CXX" LD="$LD" AR="$AR" RANLIB="$RANLIB" CPP="$CPP" AS="$AS" OBJDUMP="$OBJDUMP" CFLAGS="$CFLAGS" LDFLAGS="$LDFLAGS" ${makejobs} ${make_build_args} ${make_build_target}' exited with 2
=> ERROR:   in do_build() at common/build-style/gnu-makefile.sh:9
```
I know that xlint throws up errors on this template as well, I thought I should fix those after solving the build errors. Any other suggestions for improvement are welcome as well!

As for `qtdeploy`, the best I can figure is that it's a tool provided by [this repository](https://github.com/therecipe/qt). Unfortunately, the repo has no releases, so the bindings and tools it provides can't be packaged. ericonr on IRC said that it might be possible to build without `qtdeploy`, but I haven't understood the Makefile well enough yet to figure out how to do that.
