description:
Explicitly print a fs image filename on "fs image is too big" errors.

This will help future analysis of build errors caused by bloated
embedded ramdisk images and possible but unexpected other binaries.

Proposed on port-mips@ in discusson about ews4800mips daily build errors:
 https://mail-index.netbsd.org/port-mips/2020/06/14/msg000950.html
and "Yes please!" from martin@.
