createrepo-c: Fix function declaration bug found with clang

clang is stricter about function parameter types in its functions and
errors out.

error: incompatible integer to pointer conversion initializing 'gchar *' (aka 'char *')

Real problem is in createrepo_c code where funciton definition and
declaration scopes are different

+Subject: [PATCH] Move cr_compress_groupfile outside WITH_LIBMODULEMD
+
+This function is used in code which is not conditional under WITH_LIBMODULEMD
+therefore the declaration should also match its definition scope
+
+Fixes build issues flagged by clang
