[issue11386] Fix exception thrown by bytearray.pop() for empty bytearrays

[Raymond Hettinger]

Raymond Hettinger <rhettinger at users.sourceforge.net> added the comment:

The patch looks fine.  Please apply and backport.

Also, please search all other pop() methods in the standard library to see if this bug occurred anywhere else.  Popping from an empty container should be a LookupError, either IndexError for sequences or KeyError for mappings.
