Bug #56774 "debug" tests during RPM + PKG build don't use the debug server

Description:
Affected: Linux RPM builds + Solaris PKG builds

This is a part of the RPM test log of the 5.5.6-rc build
on SLES 11 (x86_64):

=====
...
Completed: Failed 1/1 tests, 0.00% were successful.

Failing test(s): nist.nist_all

The log files in var/log may give you some hint of what went wrong.

Similar lines are in the test log of Solaris-PKG builds.

Note that the script tries to switch from the default (optimized) server to the debug server by using "mv ../bin/mysqld*" commands which fail because there is no server binary in "../bin", but the script just continues and reports the next test run to be done using the debug server.

In a tar.gz test log, the path is different ("bin/" as opposed to "../bin/"), and the commands succeed:

How to repeat:
Look into a RPM test log of the cmake build process.

I found the cause:
The test script uses a wrong path name when trying to put the debug server in the default place.

A fix was used successfully in re-tests, I will now commit it.

Fixed by this patch:
