Drop remaining references to removed source lines in break1.c and ur1.c

Drop remaining references to removed source lines in break1.c and ur1.c

In some .exp files it was missed to remove the references to
eye-catchers like "set breakpoint 9 here" when the non-prototype
function header variants they belonged to were deleted.  This patch
cleans this up.

gdb/testsuite/ChangeLog:

	* gdb.base/condbreak.exp: Drop references to removed non-prototype
	function header variants in break1.c.
	* gdb.base/ena-dis-br.exp: Likewise.
	* gdb.base/hbreak2.exp: Likewise.
	* gdb.reverse/until-precsave.exp: Drop references to removed
	non-prototype function header variants in ur1.c.
	* gdb.reverse/until-reverse.exp: Likewise.
