git-p4 shouldn't attempt to store symlinks in LFS

git-p4.py would attempt to put a symlink in LFS if its file extension matched git-p4.largeFileExtensions. Git LFS doesn't store symlinks because smudge/clean filters don't handle symlinks. They never get passed to the filter process nor the smudge/clean filters, nor could that occur without a change to the protocol or command-line interface. Unless Git learned how to send them to the filters, Git LFS would have a hard time using them in any useful way. Git LFS's goal is to move large files out of the repository history, and symlinks are functionally limited to 4 KiB or a similar size on most systems.
