tests: fix spurious failure with FreeBSD make and Yacc in VPATH

* tests/subpkg.test: Some cosmetic adjustments.  Move the tests
checking that $(YLWRAP) is defined and installed properly when
ylwrap is in a default auxdir found in a parent package ...
* tests/subpkg-yacc.test: ... into this new test, which carefully
avoids to trigger the known bug#7884 (combo FreeBSD make plus Yacc
plus VPATH build).
* tests/Makefile.am (TESTS): Update.
