Make archquery use the same VM as DDMS/Traceview

archquery is used to figure out whether the VM is 32 or 64 bit, but on
MacOS X, it used the normal "java" command while the application was
forced to use java 1.5

This could lead to cases where archquery ran in 1.6 64bit but the app
in 1.5 32 bit, creating a mismatch and make the app using the wrong
SWT version.
