[bug#61253] [PATCH core-updates 00/19] Add license files missing from font packages

[Simon South <simon@simonsouth.net>]

This patch series adds license files missing from 29 font packages[0] that use
font-build-system.  It also modifies font-build-system to expose the
#:license-file-regexp argument it inherits and provide a custom, more specific
default value for it, both of which should help future font-package authors
ensure license files are installed correctly.

For testing, note you may need to first apply the patches attached to issues
61039, 61119 and 61120[1] to avoid unrelated build failures.  In preparing
this current set of patches I considered a license file "missing" if it is the
only relevant file in the source package, is referred to by another license
file or qualifies the license in some way (for instance, a README file
specifying an exception to the GPL).

In cases where I've changed a package source's fetch method (such as from
"url-fetch/zipbomb" to "url-fetch") this was done to ensure the correct
working directory is selected when the install-license-files build phase runs,
and is related to the unpack phase's magical behaviour of choosing an
arbitrary subdirectory to enter before it completes[2].

I've tested these changes on x86-64 and AArch64 and everything seems fine.
