git-p4: fix Git LFS pointer parsing
Git LFS 1.2.0 removed a preamble from the output of the 'git lfs pointer' command [1] which broke the parsing of this output. Adjust the parser to support the old and the new format. Please note that this patch slightly changes the second return parameter from a list of LF terminated strings to a single string that contains a number of LF characters.
