Subject: [PATCH] u-boot: fix script format when !CONFIG_UBOOT_NEWAPI

When !CONFIG_UBOOT_NEWAPI and hence linking against U-Boot's
tools/env/lib.a, SWUpdate's bootloader/uboot.c calls lib.a's
fw_parse_script() which expects input to be in format, quoting:
 ...
 * Each line has a couple with name, value:
 * <white spaces>variable_name<white spaces>variable_value

This was changed in SWUpdate by commit dab1b70 "Unify bootloader
script format" to be '='-separated instead of space-separated,
hence breaking the integration with the "old" libubootenv binding.
