commit 66573786 (main/lua-json4: install into lua/common, remove
subpkgs, add rock_manifest) renamed the lua5.x-json4 packages and added
a provides for backwards compatibility. But the build time dependencies
does not resolve the provides so builder will fail figure out the build
time order.

We work aorund this by adding an explicit depend of lua-json4, without
the lua version, so we no longer depend on proper provides resolving.

This commit updates $license variable in all APKBUILDs to comply with
short names specified by SPDX version 3.0 [1] where possible. It was
done using find-and-replace method on substrings inside $license
variables.

Only license names were updated, not "expressions" specifying relation
between the licenses (e.g. "X and Y", "X or Y", "X and (Y or Z)") or
exceptions (e.g. "X with exceptions").

Many licenses have a version or multiple variants, e.g. MPL-2.0,
BSD-2-Clause, BSD-3-Clause. However, $license in many aports do not
contain license version or variant. Since there's no way how to infer
this information just from abuild, it were left without the variant
suffix or version, i.e. non SPDX compliant.

GNU licenses (AGPL, GFDL, GPL, LGPL) are especially complicated. They
exist in two variants: -only (formerly e.g. GPL-2.0) and -or-later
(formerly e.g. GPL-2.0+). We did not systematically noted distinguish
between these variants, so GPL-2.0, GPL2, GPLv2 etc. may mean
GPL-2.0-only or GPL-2.0-or-later. Thus GNU licenses without "+" (e.g.
GPL2+) were left without the variant suffix, i.e. non SPDX compliant.

Note: This commit just fixes format of the license names, no
verification has been done if the specified license information is
actually correct!

Most of these updates is based on data from https://repology.org/,
detection based on permanent redirect from http:// to https://.

$source urls are updated when they contain $url as substring.

This conforms to wiki documentation regarding package creation:
http://wiki.alpinelinux.org/wiki/Creating_an_Alpine_package#license

ACF does not support multiple parallell lua versions anyways so only
require lua 5.2 for now.

fixes #4066

the cgit update broke every download url.
