m4: fix readline macro

Browse source 
The macro always overwrites LIBS and the result is that every binary
links against libreadline.

Instead, save the library to READLINE_LIBS.

See also: 94274c6fcd ('build: fix wrongly linking against libreadline in all applications')

Fixes: af360238be ('m4/ax_lib_readline.m4: Update after running aclocal')
