configure.ac: search for ncurses' tinfo library if available

ncurses can be built to split out the lowlevel terminfo library
from ncurses library. In this case there's a libtinfo.so file
alongside the usual libncurses*.so files.
This patch adds tinfo to AC_SEARCH_LIBS when ncurses support
is enabled. Without this patch configure silently fails to find
tgetflag and thus does not link to ncurses at all.
I've tested this change on both, ncurses with separate tinfo lib
and ncurses without separate tinfo lib and in both cases joe
successfully links against ncurses.
