Can't build on Ubuntu 14.04

Hi, just a heads up, I'd been able to build an old Ubuntu 14.04 Dockerfile that uses mod_tile until until this recent commit, after which I get an error:

#18 8.225 config.status: executing libtool commands
#18 8.305 depbase=`echo src/daemon.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
#18 8.305       gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I./includes  -pthread   -g -O2 -MT src/daemon.o -MD -MP -MF $depbase.Tpo -c -o src/daemon.o src/daemon.c &&\
#18 8.305       mv -f $depbase.Tpo $depbase.Po
#18 8.330 src/daemon.c:47:33: fatal error: iniparser/iniparser.h: No such file or directory
#18 8.330  #include <iniparser/iniparser.h>

#18 8.330 compilation terminated.
#18 8.387 make: *** [src/daemon.o] Error 1

Not a significant issue, but just thought I'd share.

Please use version 0.5 of mod_tile for Ubuntu versions prior to 18.04 Bionic Beaver. master is to keep up with recent versions, currently making sure it works best with the current Ubuntu LTS Focal Fossa 20.04.

By the way mod_tile and renderd are going to be even included in the next Ubuntu release 21.04 - there won't be a need to compile it anymore.
