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.
