Log:
Force use of 'mv -f' when moving aside hbase logfiles

Summary:
We saw a case where the hbase startup script wouldn't finish because it
couldn't move logfiles out of the way, and would throw the session into
interactive mode.

The problem is caused because the script uses 'mv' with no arguments, and so it
will inherit any shell aliases for the default. This changes 'mv' to 'mv -f'

Test Plan:
No longer thrown into interactive mode, and the files are moved out of the way.
