package/ghostscript: security bump to version 9.56.1

Fix CVE-2022-2085: A NULL pointer dereference vulnerability was found in
Ghostscript, which occurs when it tries to render a large number of bits
in memory. When allocating a buffer device, it relies on an
init_device_procs defined for the device that uses it as a prototype
that depends upon the number of bits per pixel. For bpp > 64,
mem_x_device is used and does not have an init_device_procs defined.
This flaw allows an attacker to parse a large number of bits (more than
64 bits per pixel), which triggers a NULL pointer dereference flaw,
causing an application to crash.
