Add command to import U-Boot binaries from an external location

This option is useful if the user already builds U-Boot in a directory
not managed by the tegra-uboot-flasher manifest. This may happen when
an active U-Boot developer wishes to use the flasher scripts without
relocating their U-Boot development, or when performing separate
automated builds of U-Boot and the flasher, with the flasher build
picking up the result of an abitrary U-Boot build under the control of
the automated build system.
