install: Make sure uvesafb can be loaded.
Fixes <https://issues.guix.gnu.org/60010>.
Reported by pelzflorian (Florian Pelz) <pelzflorian@pelzflorian.de>.
Previously, the 'modprobe' executable would try and fail to load the
module from /lib/modules/*. Set 'LINUX_MODULE_DIRECTORY' to make sure
'modprobe' looks for the module in the right place.
* gnu/system/install.scm (uvesafb-shepherd-service)[modprobe]: New
variable.
In 'start' method, invoke it instead of KMOD/bin/modprobe.
