gnu: u-boot: Fix target/system comparison in 'make-u-boot-package'. 

Until now, running, say:

  guix build -e '(@@ (gnu packages bootloaders) u-boot-a20-olinuxino-micro)' \
    -s armhf-linux

on an x86_64-linux machine wouldn't have the desired effect
because (%current-system) would return "x86_64-linux" when 'same-arch?'
was evaluated.  This fixes that.

* gnu/packages/bootloaders.scm (make-u-boot-package)[same-arch?]: Turn
into a thunk so that (%current-system) is evaluated in the right
context, and adjust callers.  Use 'string=?' instead of 'string-prefix?'.
