xinput-calibrator: move it from meta-oe to oe-core

People using xserver-xorg that need to calibrate their touchscreen
devices would also need meta-oe. Bringing the recipes to oe-core will
make it easier for them.

Aditionaly:
 * drop xterm RDEPENDS. Terminal is not needed to run the menu item;
 * change xinput_calibrator_pointercal.sh so that it can be run as
   normal user: pointercal.xinput is saved to ~/.pointercal/ and it will
   be used when the system boots;
 * have the calibration run through an Xsession file;
 * remove the systemd service since calibration is run by Xsession;
 * do not install pointercal.xinput if it's the default one;

[YOCTO #4416]
