Faketime library fixes deployed to CI and few other small (generally hived unrelated) changes

1. faketime version switched to the local one containing fixed bugs in timer handling

2. reduced faketime speedup on datagen test group, adjusted timeout value

3. Seems that DeepDiff[murmur] extension is not available yet in given installation form: WARNING: deepdiff 5.8.1 does not provide the extra 'murmur'
   Due to DeepDiff troubleshooting docs, mumrmur installation procedure has been changed to the one mentioned in doc: https://zepworks.com/deepdiff/current/troubleshoot.html

   Required by HAfAH pattern tests.
