configure.ac: Fix C(PP)FLAGS for BSD build

If we pass CFLAGS params to configure, then the CFLAGS set inside
configure.ac are not applied and the build fails if -Werror is enabled
because then BUILDING_LIBOSMOCORE is not defined.

Seeing the following output at configure time in FreeBSD build:
./configure: CFLAGS+= -fsanitize=address -fsanitize=undefined: not found
./configure: CPPFLAGS+= -fsanitize=address -fsanitize=undefined: not found
./configure: CFLAGS+= -DBUILDING_LIBOSMOCORE -Wall: not found
./configure: CPPFLAGS+= -DBUILDING_LIBOSMOCORE -Wall: not found
