This patch adds a new security attribute to Smack called
SMACK64EXEC. It defines label that is used while task is
running.
Exception: in smack_task_wait() child task is checked
for write access to parent task using label inherited
from the task that forked it.
Fixed issues from previous submit:
- SMACK64EXEC was not read when SMACK64 was not set.
- inode security blob was not updated after setting
SMACK64EXEC
- inode security blob was not updated when removing
SMACK64EXEC
