wic: do not remove build dir in source plugins

Interesting bug was found during implementation of 'include'
parser command.

Build directory was removed in do_configure_partition method of
bootimg- source plugins. This can cause removal of previously
prepared partition images if /boot partition is mentioned after
other partitions in .ks file.

Moved work directory removal to direct.py before processing
partitions.
