[ASAN]Increasing switch create timeout for ASAN images (sonic-net#2777)

**What I did**
When running ASAN images with low CPU systems, due to the additional overhead associated with ASAN, it results in switch create timeout as seen in logs below. Hence increasing the **switch create timeout to 2x for ASAN builds.** e.g. For regular switch scenario, the timeout will be 120 seconds  instead of 60 seconds.

```

Apr 18 20:24:46.817552 arc-switch1004 ERR swss#orchagent: :- main: Failed to create a switch, rv:-1

```

**Why I did it**
To avoid timeout to create switch when testing ASAN builds with lower CPU systems

**How I verified it**
Loaded the build with changes and verified no issues are seen
