vim: fix go filetype detection

The filetype needs to be set during BufRead in order for the did_filetype() check to prevent the file being detected as a conf file.  One example where this can occur is if a cgo file has a #include at the top of the file.  The # is detected in vim's generic configuration (conf file) toward the bottom of filetype.vim
