uboot-sign.bbclass: fix some install commands
A "install -d" command is missing when dealing with
${UBOOT_NODTB_BINARY} in install_spl_helper function, this can lead
to invalid install error saying:
| install: cannot create .../usr/share/u-boot-nodtb-2021.04-r0.bin': No such file or directory
Let's drop all "install -d" and replace them with "install -Dm" in
install_helper/install_spl_helper functions.
