The install_bin from /lib/upgrade/common.sh is no longer creating the
symlinks when a secondary parameter is added. But the fw_setenv program was
always copied this way to the ramdisk for the upgrade.
Instead, this should be done using RAMFS_COPY_* like on all other
platforms.
Fixes: 438dcbfe74 ("base-files: automatically handle paths and symlinks for RAMFS_COPY_BIN")
