linux-modules: Raise an error when a kernel module cannot be found.
Previously we'd get an unhelpful backtrace like this: In gnu/build/linux-modules.scm: 184:47 4 (recursive-module-dependencies _ #:lookup-module _) 98:14 3 (module-dependencies _) 85:18 2 (modinfo-section-contents _) In ice-9/ports.scm: 439:11 1 (call-with-input-file #f #<procedure get-bytevector-al?> ?) In unknown file: 0 (open-file #f "r" #:encoding #f #:guess-encoding #f) ERROR: In procedure open-file: Wrong type (expecting string): #f builder for `/gnu/store/…-linux-modules.drv' failed with exit code 1 * gnu/build/linux-modules.scm (find-module-file): When MODULE cannot be found, raise an error instead of returning #f. This is more useful to the user.
