Fix ensure => absent with path => set.

The current code doesn't correctly account for an absent with a
path set, incorrectly trying to remove $name instead.  Fixing this
raised the issue that fragments left with no ensure will fail when
absent is set as the fragdir is deleted.

As a workaround for this we check the `ensure` parameter from the
concat{} resource with getparam() and then pass that to the fragment
if no specific ensure was passed in.  This effectively ensures
fragments inherit their parents ensure status.
