Encountered several testcase failures when running `ninja check-all`. It
was due to the full path name were shown in the error message instead of
the binary name, and therefore causing the check string mismatch.
The machine was running CentOS 9 with binfmt_misc setup that uses
qemu-aarch64 (8.1.2). Built and ran the unittest as aarch64 host
(through qemu user).

Fail gracefully instead. Prevent further misuse by enforcing the factory builder
instead of the constructor.
