package/uboot-tools: add option to install fit_check_sign

This commit adds an option to install fit_check_sign to target for fit
image validation.

This will allow a fit image to have its signature and hashes validated
from Linux, assuming a device-tree of keys (the same as which is in
u-boot) is available.
