compilers: fix regression in logging cached compile commands

In commit d326c87fe22507b8c25078a7cd7ed88499ba7dc1 we added a special
holder object for cached compilation results, with some broken
attributes:

- "command", that was never set, but used to print the log

- "args", that was set to some, but not all, of the information a fresh
  compilation would log, but never used

Remove the useless args attribute, call it command, and use it properly.
