fix: booting orangepi5 from nvme drive

For some reason test -e command that checks for armbianEnv.txt file existence fails to mount the first partition.
This leads to ignoring of all boot environment, including the critical rootdev variable.
This variable is hardcoded to /dev/mmcblk0p1 which works for the default sdcard case, but doesn't for nvme (and likely sata)
At the same time the load command that comes after that works well

Therefore the idea behind this change is to not test for file existence and attempt to load it instead
on success - import the env variables
