rcc.cpp: Use a QMultiHash explicitly if insertMulti() is being used

Apply the rcc part from qtbase/c7e35ffe69a73bb144618714313673f0d0c28394
to the copy of the rcc code used in Qt Designer, fixing:

shared/rcc.cpp: In member function 'bool RCCResourceLibrary::addFile(const QString&, const RCCFileInfo&)':
shared/rcc.cpp:605:47: warning: 'QHash<K, V>::iterator QHash<K, V>::insertMulti(const Key&, const T&) [with Key = QString; T = RCCFileInfo*]' is deprecated: Use QMultiHash for hashes storing multiple values with the same key. [-Wdeprecated-declarations]
