fstab-generator: use DefaultDependencies=no for /sysroot mounts

Browse Source 
Otherwise we can end up with an ordering cycle. Since d54bab90, all
local mounts now gain a default `Before=local-fs.target` dependency.
This doesn't make sense for `/sysroot` mounts in the initrd though,
since those happen later in the boot process.

Closes: #12231
