RFC: moving sysutils/fusefs-kmod to base system

Unless I understand how the kernel does stuff there is no penalty for 
having unused modules (except the size of the kernel that needs to be 
loaded).   Keeping in mind that unless I am not reading stuff corectly 
fusefs-kmod is the only FS related module that is not in the base 
system.   Since any fundamental changes in the generic FS API seems to 
break fusefs-kmod, and cause some very nasty effects that are almost 
impossible to trace to fusefs-kmod (machine freezes so no output or core 
dump)  it seems to make sense to move it to  the base system  (after all 
we already do this with third party FS code like x/zfs)  by moving it we 
force it to always compile instead of breaking (of course there can be 
other issues but as the FS API is updated fusefs-kmod is also updated to 
use the new API)
