[Dev] PKGBUILD for gmnisrv-git (a gemini server)

[bill-auger]

for completeness toward a new contributor, i should mention that
you could simply paste the raw patch text into the email body -
that is what git send-email does

i am not among them; but most people do not mind getting patches
that way - some people (RMS comes to mind) prefer to see the
patch text directly in the email body, not as an attachment
certainly for small changes

most PKGBUILDs (entire abslibre directories) are very small
files; so it is less important for abslibre, how/where the
changes arrive
