Title: fix tool.vim::go#tool#BinExists()

see vim manual about executable(): This function checks if an executable with the name {expr} exists. {expr} must be the name of the program without any arguments. So if there is some blank chars around a:binpath, the called result will be -1, that's incorrect.
