lldpd: fix autoreconf failure
The lldpd sources ship a modified local AX_LIB_READLINE M4 macro which
conflicts with the official macro shipped by autoconf-archive.
Due to the official macro having the same name and a higher serial
number, autoconf will prefer including that one instead of the local
copy, preventing the substitution of @READLINE_LIBS@ in Makefile.in
templates, ultimately leading to the following build failure when
linking lldpcli:
...-gcc: error: READLINE_LIBS@: No such file or directory
Avoid this problem by renaming the locally shipped macro to not clash
with the official implementation anymore.
