ModSecurity fails to build on Buildroot with MaxMind enabled

[frankvanbever]

Describe the bug

ModSecurity v3.0.5 fails to build on Buildroot when MaxMind is enabled. Buildroot depends on pkg-config for the cross compilation to work. Upstream MaxMind uses libmaxminddb as the pkg-config package name https://github.com/maxmind/libmaxminddb/blob/main/src/libmaxminddb.pc.in.

This was removed from the possible candidates in 785958f9b5089b918c7d054cbcc2fe4a3c7b3788.

Reverting this commit (+ Autoreconf) fixes the build failure.
