libcupsfilters: patch CVE-2025-64503

Browse Source 
Details: https://nvd.nist.gov/vuln/detail/CVE-2025-64503

Pick the patch that explicitly refernces the CVE ID in its message.
(The NVD advisory mentions only the cups-filters patch, but
the developer indicated the CVE ID in the libcupsfilters patch also)

Between this recipe version and the patch the project has decided to
eliminate c++ from the project, and use c only. The patch however
is straightforward enough that it could be backported with very small
modifications.

Subject: [PATCH] Fix out-of-bounds write in cfFilterPDFToRaster()
From: Till Kamppeter <till.kamppeter@gmail.com>
PDFs with too large page dimensions could cause an integer overflow and then a too small buffer for the pixel line to be allocated.
Fixed this by cropping the page size to the maximum allowed by the standard, 14400x14400pt, 200x200in, 5x5m
