[LPIA Hardy LUM, netbook-lpia branch] unionfs: enable delete=all unionfs mount option

[Colin Ian King]

For: Hardy Lum, netbook-lpia branch 

LP#445673

https://bugs.launchpad.net/ubuntu/+bug/445673

unionfs does not have the delete=all mount option compiled
in. Enable this by adding -DUNIONFS_DELETE_ALL to CFLAGS.

Without the delete=all option configured one cannot mount
a unionfs without having to fallback on using whiteouts which
can consume a considerable amount of inodes to mark deleted
files. This can cause problems on unionfs systems with limited
inode reservations where storage is very limited.
