Install qemu TCG plugins to ${INSTALL_DIR}/lib/qemu/plugins

So that we can use some plugins to do profiling. For example, use
libinsn.so to count dynamic instructions.

I think it might be sufficient to use --enable-plugins and/or $(MAKE) -C $(notdir $@) plugins. Then we don't need to do manual copying.

I don't know if I did something wrong or it just doesn't install plugins. I have tried this method before but I can't find these plugins in qemu installation dir.

I've sent a patch to the qemu list to include the plugins when installing:

Then we don't need this PR anymore if that is merged. Thanks! :-)

Since you closed this PR:
Having the patch in QEMU is the preferred solution.
However, if QEMU does not accept the patch, then I am fine with this PR.
