Profiling points updated, script fixed

[Issue#] LINUXNGWAP-314
[Feature] Profiling points need to be updated to better show critical launch
phases. During verification it turned out that sometimes host part of the
script fails and does not produce output graphs.
[Problem] N/A
[Cause] In one of perl scripts incorrect sorting method has been used.
[Solution] Profiling points updated. Sorting fixed.

[Verification] Run profiling scripts and check if graph is correctly generated
