sys-libs/ncurses-compat: Split ABI compat version out of ncurses

Split the :5 SONAME compatibility slot of sys-libs/ncurses into its own
package.  This is mostly meant to resolve outstanding problem with
missing slot on dependencies, ncurses being the most common offender.
By moving the compatibility into separate package, we no longer have
to worry about people mistakenly not specifying the correct slot.
