[lit] Fix internal env calling other internal commands
Without this patch, when using lit's internal shell, if `env` on a lit
RUN line calls `cd`, `mkdir`, or any of the other in-process shell
builtins that lit implements, lit accidentally searches for the latter
as an external executable.
This patch puts such builtins in a map so that boilerplate for them need
be implemented only once.  This patch moves that handling after
processing of `env` so that `env` calling such a builtin can be
detected.  Finally, because such calls appear to be useless, this patch
takes the safe approach of diagnosing them rather than supporting them.
