LogCollecteNB() not used anymore

Since 28ce0dc444 ("Main: pass in ctx"), the CI always collects logs
into cmake_targets/log/. Hence, LogCollecteNB() is never called. We can
remove it.

Further, change the cmake_targets/log/ to ci-log/, which is shorter, and
append a / on the zip path to make sure that only contents is zipped.
