package/libmodsecurity: fix build with libmaxminddb

Build with libmaxminddb is broken since bump to version 3.0.5 in commit
464d0be3 because of
https://github.com/SpiderLabs/ModSecurity/commit/785958f9b5089b918c7d054cbcc2fe4a3c7b3788

So revert this commit until upstream answer to comment to
https://github.com/SpiderLabs/ModSecurity/issues/2131

Reverting this commit requires autoreconfiguring, which itself causes
lots of warnings as configure.ac queries git to know the version of
various parts of libmodsecurity. However, it turns out that those
versions are only used to be displayed in the output of the configure
script, which is quite useless. The only one that is referenced
elsewhere is LIBINJECTION_VERSION, but it's in fact a different thing:
it is defined by others/libinjection/src/libinjection_sqli.c.

The only variable that was AC_SUBST() and therefore visible elsewhere
was MSC_GIT_VERSION, but it is not used anywhere in the code base,
except in the configure script itself.

Note that one patch is 0001 and the other 0003, because there was
already a 0002 patch.
