[bug#66099] [PATCH gnome-team v4 1/4] gnu: eudev: Update libudev version to 251.

[Vivien Kraus]

Support for version 251 is only provided as a pull request for now:

https://github.com/eudev-project/eudev/pull/253

This pull request is included as a patch, without the version bump.

Eudev now has a hardware database that installs descriptions of hardware in
/etc, but they should go to /lib prior to being used. A new phase moves the
hwdb files from /etc to /lib.

Some commits have been added since 3.2.12, in order to support search paths
for udev hwdb, and fixing a regression.

* gnu/packages/linux.scm (eudev): Update to a post-v3.2.12 commit.
[#:phases] <allow-eudev-hwdb>: New phase.
<build-hwdb>: Update accordingly.
[native-search-paths]: Add UDEV_HWDB_PATH and UDEV_HWDB_BIN.
* gnu/packages/patches/eudev-libudev-251-compat.patch: New file.
* gnu/packages/linux.scm (eudev): Use it here.
* gnu/local.mk (dist_patch_DATA): Register it here.
* gnu/packages/patches/eudev-rules-directory.patch: Rebase it.
