tests: fix spurious failure in test on Flex headers

* t/lex-headers.sh: Don't use 'yl_distcheck', simply call "make distcheck"
instead, as GNU make cannot suffer of the FreeBSD bug 'yl_distcheck' was
meant to guard against.
(Makefile.am): Don't use $(AM_MAKEFLAGS) when invoking make recursively.
This avoids a maintainer-check failure.
