docs: networking: timestamping: improve stacked PHC sentence

Browse Source 
The first paragraph makes no grammatical sense. I suppose a portion of
the intended sentece is missing: "[The challenge with ] stacked PHCs
(...) is that they uncover bugs".

Rephrase, and at the same time simplify the structure of the sentence a
little bit, it is not easy to follow.
