    image.bbclass: do exact match for rootfs type
    
    Do exact match for rootfs type, instead of pattern match, to avoid
    unexpected build error due to redundant rootfs type build.
    
    E.g. when building ext2.gz.u-boot, both .gz.u-boot and .u-boot are matched,
    the following build error will appear, actually .u-boot is not needed.

directory
