tests/qtest/e1000e-test: Use e1000_regs.h

The register definitions in tests/qtest/e1000e-test.c had names
different from hw/net/e1000_regs.h, which made it hard to understand
what test codes corresponds to the implementation. Use
hw/net/e1000_regs.h from tests/qtest/libqos/e1000e.c to remove
these duplications.
