BUG#52341: PB2: rpl tests started taking three times more time on

           linux x86_64 max 

Rpl tests were surprisingly taking too long when server was built
using cmake on linux. This was because cmake counter part of
patch for WL#4949 was not defining SIGNAL_WITH_VIO_CLOSE flag,
which had negative impact on the time needed to stop the slave IO
thread on STOP SLAVE command.

We fix this by deploy the missing SET command on configure.cmake.
