Building -next with clang-android reveals it is using a version of
openssl that does not support CMS_NO_SIGNING_TIME:
  scripts/sign-file.c:282:4: error: use of undeclared identifier 'CMS_NO_SIGNING_TIME'
    282 |                         CMS_NO_SIGNING_TIME |
        |                         ^~~~~~~~~~~~~~~~~~~
This is a simple bug in the kernel that is being addressed [1] but for
the same reason that the majority of toolchain containers were bumped to
Debian 13 in commit  46280e2  ("runtime: Migrate toolchains from Debian 12
to Debian 13 base containers"), update clang-android's base image to
Debian 13 to avoid future issues such as this.
