Support dracut's rdloaddriver= option for force-loading kernel modules
at boot time. This keeps loader's options in line with dracut and deals
with the customer cases where they want to force the loading of a
particular kernel module before udev scans the system.
The following examples are valid:
rdloaddriver=module
rdloaddriver=module,module,module
Unlike dracut, you may not specify more than one rdloaddriver= option on
the command line. If you specify multiple, the installer uses the last
one specified and ignores the preceeding ones.
"rdloaddriver" itself is case-insensitive, but the kernel module name
must exactly match what it's called.
