Created the Structure.test_alt_loc_missing system test.

This is to test that the internal relax PDB reader raises an error when a PDB file is encountered
with alternate location indicators but the alt_loc argument has not been specified.

Fix for bug #20470 (https://gna.org/bugs/?20470).

The structure.read_pdb user function now accepts the alt_loc argument for specifying the alternate
location indicator to read. This is used by the internal PDB reader. The bug was caught by the
Structure.test_bug_20470_alternate_location_indicator system test.
