Subject: [PATCH 3/3] Linux: Do not force 64-bit `time_t` on 32-bit archs with
 system libarchive

Commit 1b9e8f833f (Linux: Compile with 64-bit time_t even on 32-bit
architectures, 2025-06-26, v4.1.0-rc2~16^2) broke running with a
system-provided libarchive that uses a 32-bit `time_t`.  If CMake
is configured to build with a system libarchive, assume the user
has taken responsibility to match `time_t` sizes.

Fixes: #27448
