input-leap: Update to latest HEAD

[Koston-0xDEADBEEF]

Despite there now being official releases of input-leap, code quality remains unchanged and there is unfortunately still no added value from sticking to the release versions.

This update disables GUI variant due to intrusive build changes in project upstream, which need to be fixed before re-enabling it.

Verification

Have you

• followed our Commit Message Guidelines?
• squashed and minimized your commits?
• checked that there aren't other open pull requests for the same change?
• checked your Portfile with port lint?
• tried a full install with sudo port -vst install?
• tested basic functionality of all binary files?
  • Tested both client and server pairs with FreeBSD, using same version of input-leap and additionally with the last release of Barrier.
• checked that the Portfile's most important variants haven't been broken?
  • GUI variant is broken, but it's not important.

This software is a bit of a headache. This is the best I can do for now, as I've already spent a lot more time on this than I'd allocated. Before next port update, several fixes are needed upstream.

Edit: Reason for using HEAD instead of latest release is that the latest release is effectively just an older HEAD. Release was a surprise to everyone except the maintainer who made it - by just tagging latest HEAD.

Removed a few unused dependencies: ghc-filesystem is only needed if tests are built (always disabled), and either pkgconfig is only needed by GUI build or is entirely unused.

Also slightly re-worded post-install notes to reflect my experience that installing a new version no longer requires re-registering its permissions. How, why or when this changed is unclear.
