Bug#1050033: renderdoc: Build with archive's swig

[Bastian Germann]

Source: renderdoc
Version: 1.27+dfsg-1
Severity: important
Control: block 999924 by -1
renderdoc includes an outdated copy of swig that is used for the build.
Please build depend on Debian's swig instead. That has #999948 already 
fixed.
