loplugin:override: No more need for the "MSVC dtor override" workaround

The issue of 362d4f0cd4e50111edfae9d30c90602c37ed65a2 "Explicitly mark
overriding destructors as 'virtual'" appears to no longer be a problem with
MSVC 2013.

(The little change in the rewriting code of compilerplugins/clang/override.cxx
was necessary to prevent an endless loop when adding "override" to

  OOO_DLLPUBLIC_CHARTTOOLS    virtual ~CloseableLifeTimeManager();

in chart2/source/inc/LifeTime.hxx, getting stuck in the leading
OOO_DLLPUBLIC_CHARTTOOLS macro.  Can't remember what that
isAtEndOfImmediateMacroExpansion thing was originally necessary for, anyway.)
