readline: fix pkgconfig usage

ncurses is built with wide support enabled, which enables libncursesw.
The problem is, the ncurses build system only supplies ncursesw or
ncurses.pc but not both. The other problem is, the readline build tests
for libncurses before the w variant, making its pc file unusable as
there is no ncurses.pc file to satisfy the Required: ncurses section.

Just override the library.
