platform2: sweep the lint errors identified by the updated linter
cpplint.py has been updated and identified new issues in existing
code. Stuff like overridden functions that specify 'override' should
not be marked as 'virtual', and constructors with no parameters
should not be marked as 'explicit'.
BUG=None
TEST=cpplint.py `find ./platform2 -name *.cc -or -name *.h`
