"make install" should replace binary without requiring server shutdown

[ScottKevill]

In src/Makefile, change:

INSTALL= cp -p

to:

INSTALL= cp -pf

Updates would be a lot easier if they could be done without downtime. Then the server only has to be restarted for the new update to take effect. This is especially useful if you already have supervisor/manager processes that auto-restart a redis server.

Without it, you get:

cp -p redis-server /usr/local/bin
cp: cannot create regular file `/usr/local/bin/redis-server': Text file busy
make[1]: *** [install] Error 1
make[1]: Leaving directory `xxxxx/redis-2.4.7/src'
make: *** [install] Error 2
