[Buildroot] [git commit] fs/common: allow filesystems to set the name of their output file

commit: https://git.buildroot.net/buildroot/commit/?id=21c6fb2589fb36d0d9367efe906c94da67cbf009
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
