Replace os.mkdir with os.makedirs

Replace os.mkdir with os.makedirs

/b in SWARMING_BOT_DIR and /var/log/messages in LOGS_DIR might not
exist. This will prevent os.mkdir from constructing the whole path,
which will in turn prevent the bot from bootstrapping.

No L-G-T-M from a valid reviewer yet.
CQ run can only be started once the patch has received an L-G-T-M from a full
committer.
Even if an L-G-T-M may have been provided, it was from a non-committer,_not_ a
full super star committer.
Committers are members of the group "project-infra-committers".
Note that this has nothing to do with OWNERS files.
