Delete unnecessary -d options from umount in unit tests.

The -d option to umount is unnecessary in cases where the original
mount was created with '-o loop' (it says so in the man page).
Moreover, there's a demonstrable bug when using 'umount -d' in this
case:  umount complains that it's unable to delete the loop device
in this case.  This change silences those messages.

The demonstrated bug in umount is a plausible explanation for build
failures characterized by unexpected failures of 'mount -o loop';
see the BUG, below.

BUG=chromium-os:24975
TEST=Run the unit test, verify it still works.
