avoid parallel "make distcheck" failure due to two run-in-src/ rules

Move the check-AUTHORS rule from "syntax-check" to "check".
* maint.mk (local-checks-available): Remove check-AUTHORS.
(check-AUTHORS): Remove rule.
* src/Makefile.am (CLEANFILES): Add $(no_install__progs),
since they too are built sometimes.
(check-AUTHORS): Split a longer-than-80 sed command.
(../AUTHORS): Remove obsolete rule.
