Commit 46e01c0e1d ("u-boot: Avoid building U-Boot-only binman images")
added a patch that prevents an error while building U-Boot, due to some
U-Boot images needing a copy of BL31 that we are not passing in.
Removing build instructions for these images isn't really necessary,
when we can instead tell the build tool that it shouldn't exit with an
error. It checks a BINMAN_ALLOW_MISSING environment variable for this,
but just unconditionally replace the check with the argument.
