package/texinfo: remove package

Having checked that binutils doesn't need to depend on host-texinfo...

  http://patchwork.ozlabs.org/patch/515914/

...and having fixed gdb to not build the documentation...

  http://patchwork.ozlabs.org/patch/515821/

...we can now safely remove this host package since there aren't any
packages depending on it.
