Replace matchstrpos() with match() + split() for backwards compatibility

matchstrpos() was added to Vim as patch 7.4.1685:
http://ftp.vim.org/vim/patches/7.4/7.4.1685

Older but still vendor-supported operating systems (such as Ubuntu 14.04
LTS and derivatives) ship versions of Vim that predate this patch.
Replacing matchstrpos() allows vim-gutentags to continue to work with
these older versions of Vim.
