Subject: [PATCH] artifact-uboot: add UBOOT_GIT_CACHE_TTL to control git ref
 memoization (fixes #7710)

By default the git ref of BOOTSOURCE/BOOTBRANCH is memoized for 3600 seconds,
so pushing new commits to a tracked branch is not picked up until the cache
expires.  Add UBOOT_GIT_CACHE_TTL, mirroring KERNEL_GIT_CACHE_TTL in
artifact-kernel.sh, so users can override this timeout (set to a low value
or 0 to always re-resolve the upstream SHA1).

As suggested by rpardini in armbian/build#7710.
