Ben Hutchings b4f6e85843 test_firmware: fix setting old custom fw path back on exit, second try
commit e538409257 upstream.

Commit 65c7923057 tried to clear the custom firmware path on exit by
writing a single space to the firmware_class.path parameter.  This
doesn't work because nothing strips this space from the value stored
and fw_get_filesystem_firmware() only ignores zero-length paths.

Instead, write a null byte.
