maint.mk: _header_without_use: fix a quoting bug and remove a bash'ism
* top/maint.mk (_header_without_use): Use "\\\\", not "\\" in the sed
expression that converts "." in a file name to "\." in the resulting
regexp. Start with a dummy statement, so that prior shell variable
definitions are expanded portably. Reported by Simon Josefsson.
