[CRIU] [PATCH 1/2] criu --help: shorten --weak-symbols descr

[Kir Kolyshkin]

Option --help should provide a brief information, like a list of
commands and options and their meaning, ideally no more than 1 line per
option. There is no need to describe nuances and details here, since
we have documentation (wiki and  man pages) for that.
