CHROMIUM: bootm: Avoid 256-byte overflow in fixup_silent_linux()

This makes fixup_silent_linux() use malloc() to allocate its
working space, meaning that our maximum kernel command line
should only be limited by malloc().  Previously it was silently
overflowing the stack.

BUG=chromium-os:21313
TEST=Manual:
1. Built with:
   USE="-cros-debug" emerge-${BOARD} \
     chromeos-u-boot \
     chromeos-bootimage
2. Flashed with:
   cros_write_firmware --board=${BOARD} /build/${BOARD}/firmware/image.bin
3. Saw that I could boot.
TEST=Manually copied unittest code (included in next checkin) to a
     C file and then ran it.  All tests pass.  Note that there is no
     automated way to run unittests like this in u-boot yet.
