[version>=5.13]: Enable CONFIG_MODULE_COMPRESS_ZSTD, else
CONFIG_MODULE_COMPRESS_GZIP.
(make-linux-libre*) [phases] {set-environment}: Set ZSTD_CLEVEL environment
variable to 19.
[native-inputs]: Add zstd.
* gnu/build/linux-modules.scm (module-regex): Add .zst to regexp.  Update doc.
(modinfo-section-contents): Extend support to Zstd compressed module.
(dot-ko): Register the 'zstd compression type.
(ensure-dot-ko, file-name->module-name, load-linux-module*)
(module-name->file-name/guess, write-module-name-database)
(write-module-alias-database, write-module-device-database): Update doc.
(module-name-lookup): Also consider zstd-compressed modules.
* gnu/installer.scm (installer-program): Add guile-zstd extension to gexp.
* gnu/system/linux-initrd.scm (flat-linux-module-directory): Likewise.
Decompress zstd-compressed modules for use in initrd.
