Fix dts output with a REF_PATH marker
Commit 8c59a97ce096 ("Fix missing labels when emitting dts format")
fixed label output, but broke output when there is a REF_PATH marker.
The problem is a REF_PATH marker causes a zero length string to be
emitted. The write_propval_string() function requires a length of at
least 1 (including the terminating '\0'), but that was not being
checked.
For the integer output, a length of 0 is valid as it is possible to have
labels inside the starting '<':
int-prop = < start: 0x1234>;
REF_PHANDLE is another marker that we don't explicitly handle, but it
doesn't cause a problem as it is fundamentally just an int.
