gpm: fix static build

Patch I developed to add support for static build into upstream build system do
not apply cleanly on 1.20.7 release, so instead of backporting it, I decided to
switch to git snapshot instead.  It allowed to get rid of three other patches
in nix expression, since they are applied upstream.
=> telmich/gpm#42

I requested proper release, but chance seems to be slim.
=> telmich/gpm#33
