common: don't fixup empty serial/machine_compatible strings
There is no point in fixing up an empty string into the kernel device
tree, yet this can happen when globalvar_add_simple_string() is called
for the variable at least once as the function replaces NULL with an
allocated empty string. globalvar_add_simple_string() was called
unconditionally for of.kernel.add_machine_compatible, which in turn
led to always fixing up an empty string as the top-most compatible.
Resolve this by having barebox_get_(of_machine_compatible|serial_number)
return NULL for the empty string as well.
Fixes: 81dd24a0946c ("of: add generic of_prepend_machine_compatible()")
Fixes: f6756e9ce6f2 ("common: add $global.serial_number with device tree fixup")
