Add more tests for corrupted data with pglz_decompress()
Two cases fixed by 2b5ba2a0a141 were not covered, to emulate the
handling of corrupted data, for:
- set control bit with a valid 2-byte match tag where offset is 0.
- set control bit with a valid 2-byte match tag where offset exceeds
output written.
Oversight in 67d318e70402.
