make-like: use seq_build.

* lib.c (make_like): Simplify implementation using seq_build,
which also lets it handle more cases.

* tests/012/seq.tl: New tests. Some existing test fixed,
including one for tuples*.

* txr.1: Documentation updated: mainly that make-like
doesn't strictly require a list argument.
