Some filesystems may want to tweak their output names, rather than using
the fixed "rootfs.foo" scheme. Add a ROOTFS_FOO_IMAGE_NAME variable for
this purpose.

Supersedes: https://patchwork.ozlabs.org/patch/988446/
Changes v1->v2:
- Prevent leading space when the filesystem gets 'imaginative', as
pointed by Yann Morin.
NOTE: https://patchwork.ozlabs.org/patch/927116/ must be upated to
document this.
