WIP gitea: update to 1.12.1, fix cross build
This template now uses gitea's upstream Makefile. This is because the
Makefile is the only official way to build. build_style=go is still used
because it provides things like GOARCH for cross building.

The upstream tarball has been changed to gitea's hand-generated ones
because of the recent sha256sum debacle, as well as their existence
(they should be preferred). In addition, create_wrksrc=yes is now
required.

gitea also now uses nodejs to generate css and js files. However, in the
tarballs, they pre-generate them. We regenerate them ourselves because
1. weird crap on musl
2. no reason not to really and it's generally better

The configuration file has been moved from /etc/gitea.conf to
/etc/gitea/app.ini. This is the appropriate location and previously it
was not being read by gitea. Also, the configuration file changes have
been moved to a .patch because the changes were getting very dense and
difficult to read in a sed.

There was a strange error with go modules which was meant to be fixed by
an upstream patch. 12030.patch is this patch. It doesn't work completely
but is fully fixed by running `go mod vendor` in pre_build (NB: the
patch is still needed). This may not be nessecary for the next release.

Internally, in the makefile, the go tags are created by the variable
TAGS. We set this. In addition, internally, they use LDFLAGS for the go
command. :( This has been patched.
