build: julia-build-system: Update for new Julia version.

* guix/build/julia-build-system.scm (generate-load-path): Delete function.
(install): Don't set JULIA_LOAD_PATH.
(precompile): Set SOURCE_DATE_EPOCH. Update calculating the
JULIA_LOAD_PATH. Adjust the 'invoke-julia' command.
(check): Set SOURCE_DATE_EPOCH. Adjust JULIA_LOAD_PATH.
