Recent commit 59356f11c1 ("perlPackages: Ensure all packages have a
license", 2022-08-22) added a license field to Perl packages where the
license was missing. The above mentioned packages got assigned
`unfreeRedistributable` license, which is not precise and makes all
packages depending on them unbuildable without `NIXPKGS_ALLOW_UNFREE`.
The packages actually have a license which SPDX calls
BSD-4-Clause-Shortened (https://spdx.org/licenses/BSD-4-Clause-Shortened.html).
In this commit, we add this license to the list of allowed licenses
and change the license field of the mentioned packages.
Closes#188103
Allows for distinction of licenses that are unfree overall but do grant the
right to redistribute. Defaults to the freeness of the license.
Note: Many unfree but are redistributable licenses aren't marked as such.
I expect that to be fixed in a distributed manner over time.

Usually we ensure using the mapAttrs call wrapping the license set that
every license has an associated shortName. A change related to legacy
aliases most likely introduced the removal of the shortName attribute
for all the legacy license names by splitting the set into two sets
connected by a record update operator -- leading to mapAttrs only
affecting the first set.
Since it used to be a valid assumption to have that every license had a
shortName attribute, we reintroduce this attribute for the legacy
aliases as well.
We recently switched to more explicit GPL license names in line
with the SPDX change and GNU Foundation recommendations:
https://www.gnu.org/licenses/identify-licenses-clearly.html
This followed up older change to use the recommended SPDX ID
18a5e8c36b
but using the `-only` variant for these deprecated licenses too
makes it harder to check for them automatically.
Let’s switch to the appropriate SPDX ID again.
