ipq806x: unset filesystem specific build command by default

Initialise the filesystem specific build command. Otherwise it will be
unintended inherit to following images and will cause a wrong image
format.

The issue is around for ages but was only recently triggered due to the
added support for the Openmesh a42.

Fixes: FS#1276
