Subject: [PATCH 1/2] Add uninstall Makefile targets

Extend the Makefiles with an uninstall target to cleanly
remove a package which was installed with 'make install'.

Additionally, ensure a 'depmod -a' is run as part of the
install to update the module dependency information.

Subject: [PATCH 2/2] Add splat module to zfs.sh script

The splat module is only needed for the spl regression tests.
But if we add it to MODULES then 'zfs.sh -u' will be able to
unload it if needed,  The downside if 'zfs.sh' will always
load it but it's overhead is minimal and in a production
setting you'll always be doing a 'modprobe zfs' anyway so
this is really just for testing.
