Fixes an undefined behaviour when the SRID is negative.

Some output example using undefined behaviour sanitizer:

Running test 'test_typmod_macros' in suite 'serialization/deserialization'.
cu_libgeom.c:35:7: runtime error: left shift of 535589632 by 3 places cannot be represented in type 'int'
cu_libgeom.c:45:14: runtime error: left shift of 280871168 by 3 places cannot be represented in type 'int'
