"make install" fails due to "text file busy" error

[Daisuke HIGASHI]

Hi,

 On Linux 'make install' fails to overwrite existing Unbound binaries
due to "text file busy" error when the unbound process is running.
This is because the Makefile uses cp(1) to install binaries.

  Here is quick fix to avoid this issue, but it might be better
to use install(1) or install.sh.

Regards,
