provisioner.py: Remove files hanging from tast runs

A device may fail to get provisioned due to limited amount of space on
stateful partition because files from tast runs can linger around. These
files must be cleared up so provisioning can hopefully have enough space
to extract the new stateful payload onto the stateful partition.

Example:

Existing files after tast runs:
localhost ~ # find /mnt/stateful_partition/ -name tast
/mnt/stateful_partition/dev_image/libexec/tast
/mnt/stateful_partition/dev_image/share/tast
/mnt/stateful_partition/dev_image/share/tast/data/chromiumos/tast
/mnt/stateful_partition/dev_image/tmp/tast

Some reflection of what amount of space it may take up:
localhost ~ # du -hsc /mnt/stateful_partition/dev_image/share/tast
/mnt/stateful_partition/dev_image/libexec/tast /mnt/stateful_partition/
dev_image/tmp/tast
453M    /mnt/stateful_partition/dev_image/share/tast
133M    /mnt/stateful_partition/dev_image/libexec/tast
12K     /mnt/stateful_partition/dev_image/tmp/tast
585M    total
