patch 9.2.0251: Link error when building without channel feature

Problem:  Compile error when building without channel feature
          (John Marriott, after v9.2.0250)
Solution: Update ifdefs and move implementation out of FEAT_JOB_CHANNEL
          (Yasuhiro Matsumoto)

Move build_argv_from_list() and mch_get_cmd_output_direct() out of
FEAT_JOB_CHANNEL guards so that system() with a List argument works
in builds that have FEAT_EVAL but not FEAT_JOB_CHANNEL (e.g.
FEAT_NORMAL without GUI).
