package/readline: bump to version 8.0

- Remove first patch (already in version) and so remove
  READLINE_AUTOCONF as configure.ac is not patched anymore
- Use the new --disable-install-examples option and remove
  READLINE_PURGE_EXAMPLES
- Remove READLINE_INSTALL_PC_FILE as readline.pc is installed since:
  http://git.savannah.gnu.org/cgit/readline.git/commit/Makefile.in?id=8e6ccd0373d77b86ed37a9a7d232ccfea3d6670c
- Remove READLINE_INSTALL_FIXUPS_SHARED (libraries are installed with
  correct rights)
- Add hash for license file

-Subject: [PATCH] configure.ac, readline.pc.in: fix Requires.private value
-
-The provided readline.pc.in hardcodes the fact that readline depends
-on the tinfo library. However, different termcap implementation are
-supported beyond tinfo. This commit improves the configure.ac script
-to define a TERMCAP_PKG_CONFIG_LIB variable, which is then used in
-readline.pc.in.
-
-This for example allows the generated readline.pc to properly contain
-"Requires.private: ncurses" when ncurses is used as the termcap
-implementation.
