platform2: Enforce virtual destructors on base classes

There have been a number of memory leak issues due to absence of
virtual destructors on base classes. Swept through the following targets:
buffet, libchromeos, webserver.

For every class defined, I did one of the following three things:

1. If the class is not meant to be derived from, marked it as 'final'.
2. If classes derived from a particular base class are not meant to be
   deleted through the base class, marked the base class's destructor
   as 'protected'.
3. Otherwise made the base class's destructor virtual.

BUG=None
TEST=`FEATURES=test emerge-link libchromeos webserver buffet`
