Resolve EPOCROOT in qt.conf using same logic as in .pro

Previously it was only possible to use EPOCROOT in qt.conf via env
variable, while qmake & configure could resolve it also via devices.xml.
Changed qt.conf parsing to support $${EPOCROOT} tag and use same
resolving logic as qmake & configure.
