disk-utils: let mkfs tools open with O_EXCL
Let mkswap, mkfs.bfs, mkfs.minix open with O_EXCL if
used on block devices to prevent writing to the device
even if they are busy (mounted).
Unfortunately, O_EXCL has zero effect for 2.4 kernels where
in-kernel code doesn't use O_EXCL-like access locks. (Tested
on RHEL3.)
