[FYI] {yacc-work} tests: minor improvements to a couple of yacc tests

[Stefano Lattarini]

The attached patch is a cleanup that ideally should have been squashed
into the commit v1.11-362-g7c0d9cb "tests: split yacc6.test, for better
separation and coverage"; but I had already pushed it when I came up
with thee changes.

Sorry for the noise,
  Stefano

tests: minor improvements to a couple of yacc tests

* tests/yacc-auxdir.test: Avoid running autoconf, it's not
needed.
* tests/yacc-line.test: Also check that the yacc-generated C
and header files do not contain "#line" directives referencing
`y.tab.c' or `y.tab.h'.  Add a couple of explicative comments.
