package/php: security bump to version 7.4.25
Fixes the following security issue:
- CVE-2021-21703: n PHP versions 7.3.x up to and including 7.3.31, 7.4.x
below 7.4.25 and 8.0.x below 8.0.12, when running PHP FPM SAPI with main
FPM daemon process running as root and child worker processes running as
lower-privileged users, it is possible for the child processes to access
memory shared with the main process and write to it, modifying it in a way
that would cause the root process to conduct invalid memory reads and
writes, which can be used to escalate privileges from local unprivileged
user to the root user.
