linux-initrd: Try several file names when looking up modules.
Fixes <https://bugs.gnu.org/31714>.
Reported by Tonton <tonton@riseup.net>.
* gnu/build/linux-modules.scm (find-module-file): New procedure.
* gnu/system/linux-initrd.scm (flat-linux-module-directory)[build-exp]:
Remove 'lookup' procedure and use 'find-module-file' instead.
* gnu/system/mapped-devices.scm (check-device-initrd-modules): Add
comment.
