Makefile: unexport 'DEVICE_TREE' environment variable

U-Boot looks for the environment variable DEVICE_TREE and uses its value if
set instead of the CONFIG_DEFAULT_DEVICE_TREE configuration option since
v2021.01, more specifically commit c0f1ebe9c1b9745e (binman: Allow selecting
default FIT configuration) - So unexport it like we do for other
"troublesome" environment variables to ensure consistent behaviour.
