Fix memory leaks in pg_combinebackup/reconstruct.c.

Browse Source 
One code path forgot to free the separately-malloc'd filename
part of a struct rfile.  Another place freed the filename but
forgot the struct rfile itself.  These seem worth fixing because
with a large backup we could be dealing with many files.

Coverity found the bug in make_rfile().  I found the other one
by manual inspection.
