Generated lightdm Xsession misidentifies KDE

[ethanwu10]

Describe the bug
(This is a bug in the files generated by Cnchi, not Cnchi itself per se)

Cnchi's /etc/lightdm/Xsession file does not properly test for KDE, and thus starts qt5ct for KDE sessions leading to issues like Antergos/antergos-packages#455. KDE now uses startkde and not plasma, so the script misidentifies it as not a QT-based DE.

The fix is simply to add startkde to the list of commands the script is checking for

To Reproduce
Steps to reproduce the behavior:
On a system with the faulty Xsession file

1. Install qt5ct (now required by antergos-common-meta as of this commit)
2. Launch a KDE session using lightdm
3. KDE themes are not applied and are unchangeable

Expected behavior
KDE theming should work
