[OE-core] [RFC PATCH 1/3] lib/bb/utils.py: add optional mode parameter to bb.utils.mkdirhier()

[Joshua Lock]

The optional parameter should be an octal file mode representing the
desired permissions of the created directory. If mode isn;t specified
use 0777. This is the default of os.makedirs() yet is not often what
the created directory ends up with due to umask affecting the call.

The use of chmod() in this patch ensures that whatever octal is
passed are the permissions the directory will have after creation.
This is a behaviour change...
