koules 1.4-6: fix for makedepends and link error

Combined package 'xorgproto' replaces 'xextproto' and 'xproto' since
nearly six years:
https://gitlab.archlinux.org/archlinux/packaging/packages/xorgproto/-/commit/34bcd7631dd89c2c1f8e91dcd76139cc014ae720

Link error fixed:
/usr/bin/ld: server.o:(.bss+0x10000): multiple definition of `controls'; koules.o:(.bss+0x7d160): first defined here
