package/cups-filters: Add patch to fix build when using poppler 0.69.0

This patch lets cups-filters only use gMemReport and memCheck functions
if poppler version less than 0.69.0

The poppler project removed the memCheck and gMemReport functions in
commits c362ab1b97f20c5b73b3bad8d52015f679178748 - Remove DEBUG_MEM
from Object since this uses RAII now and hence cannot leak.
(The existing tracking also is not thread-safe and hence unreliable.)

and

f89446f6917a869b0f1a80fcc8ce81a7213dade4 - Remove generic heap debugging
from gmem since external tools and compiler instrumentation achieve the
same effect.

The patch has been applied upstream:
