os9gen: Fix bitmap check/update where boot sector is non-zero
And on builds where the boot track is zero, most likely for
Dragon, don't check or update the bitmap because the boot
track should be reserved already.
Ideally all this should be a run-time checks of the disk
parameters and not depend on the build target. Later.
