u-boot: Fix syntax error in ${UBOOT_ENV}.scr compilation

A previous commit (a3d3c2d4ac421a0dde2a20825eab4434f16b2452) introduced
support for compiling a U-Boot boot script, but the logic contained a
syntax error which was only visible in the build log. Fix the error by
using separate []s for each expression in the if statement.
