runtime(make): Prevent makeTargetinDefine matching extra line

This fixes a bug introduced in 2a33b499a3d7f46dc307234847a6562cef6cf1d8:
When makeTargetinDefine ends with makeIdent, makeSpecTarget or
makeComment, the following line is also matched as makeTargetinDefine.

So, add keepend to prevent that just as makeTarget does.

closes: #18570
