kconfig: refactor Qt package checks for building qconf
Currently, the necessary package checks for building qconf is surrounded by ifeq ($(MAKECMDGOALS),xconfig) ... endif. Then, Make will restart when .tmp_qtcheck is generated. To simplify the Makefile, move the scripting to a separate file, and use filechk. The shell script is executed everytime xconfig is run, but it is not a costly script. In the old code, 'pkg-config --exists' only checked Qt5Core / QtCore, but the set of necessary packages should be checked.
