dtc: add option for a static build

I find myself manually compiling dtc as a staticly linked binary rather
often while porting a new device to OpenWrt as dtc is rarely included in
various vendor modifications of OpenWrt.

So, since dtc offers a convenient meson option to build it as staticaly
linked binary, lets make it a compile time option.
