Bump timeout to 4 hrs

[causten]

Seeing logs where the debug builds take 2 hours to compile.

The linking alone is taking 40 minutes...

[2024-12-08T23:07:33.108Z] make[2]: Leaving directory '/home/jenkins/workspace/AMDMIGraphX_PR-3693/build'
[2024-12-08T23:07:33.108Z] [ 31%] Built target onnx-proto
[2024-12-08T23:41:26.805Z] [ 31%] Linking CXX shared library ../lib/libmigraphx.so

I'll bump to 4 hours to let the make check timeout pop first. This will help dump additional information when it does timeout
