ptx: fix an invalid heap reference with short --width

* src/ptx.c (fix_output_parameters): Ensure line_width doesn't
go negative, which can happen when the --width is less
than the --gap-size.
* tests/misc/ptx-overrun.sh: Add a test case that triggers
with ASAN.  (Note the longer filename is needed to trigger).
Fixes http://bugs.gnu.org/25011
