libsepol: add support for filenametrans rule

This patch adds libsepol support for filename_trans rules.  These rules
allow one to make labeling decisions for new objects based partially on
the last path component.  They are stored in a list.  If we find that
the number of rules grows to an significant size I will likely choose to
store these in a hash, both in libsepol and in the kernel.  But as long
as the number of such rules stays small, this should be good.
