This will be required to implement modprobe later. The implementation
follows "man modprobe.conf" and allows options to be specified for
alias as well, thus the need for kmod_resolve_alias_options().
Example mod-a.conf:
options mod-a a=1 b=2
options mod-a c=3
alias mymod-a mod-a
options mymod-a d=4
Results in:
options mod-a a=1 b=2 c=3
options mymod-a a=1 b=2 c=3 d=4
Install commands are being concatenated with ";", but manpage is not
clean about this behavior.
