nios2: Make NIOS2_DTB_SOURCE_BOOL depend on !COMPILE_TEST 

nios2:allmodconfig builds fail with

make[1]: *** No rule to make target 'arch/nios2/boot/dts/""',
	needed by 'arch/nios2/boot/dts/built-in.a'.  Stop.
make: [Makefile:1868: arch/nios2/boot/dts] Error 2 (ignored)

This is seen with compile tests since those enable NIOS2_DTB_SOURCE_BOOL,
which in turn enables NIOS2_DTB_SOURCE. This causes the build error
because the default value for NIOS2_DTB_SOURCE is an empty string.
Disable NIOS2_DTB_SOURCE_BOOL for compile tests to avoid the error.

This allows you to specify a dts (device tree source) file
which will be compiled and linked into the kernel image.
