FindCurses: Detect and satisfy ncurses dependency on tinfo
When ncurses is built with USE=tinfo we need to find "tinfo" as a
dependency of the main library. Otherwise 'cbreak' is missing:
ld: ...: undefined reference to symbol 'cbreak'
ld: note: 'cbreak' is defined in DSO /lib/libtinfo.so.5 so try adding
it to the linker command line
See https://bugs.gentoo.org/show_bug.cgi?id=468622 for more information.
