u-boot-fslc-fw-utils: set correctly make source build dir

This partially revert commit 4e5c7e0d4959b027698e15565df7d3286e6860fa:
   u-boot-fslc: Set build dir only for u-boot recipe

Not setting the build dir in u-boot-fslc-common is breaking the build of
u-boot-fslc-mxsboot.

Instead of unsetting ${B}, set correctly the output and source dir in make
