Drop terminfo dependency and generation entirely

[bapt]

Summary

The terminfo definition is not needed anymore:

• in all freebsd version supported: termcap do have a definition of rxvt-unicode
• ncurses itself in it database also provides the terminfo definition for rxvt-unicode

[thierry]

There is no more terminfo file, and also plist must be patched:

update the plist

[bapt]

previous update nuked the Makefile change by accident

OK.
