Jean-Marc Lasgouttes 642b4acca1 Let TeXFiles.py handle symbolic links.
Nix (https://nixos.org) is a Unix package manager, which can be used to
install LaTeX on macOS. A peculiarity of Nix is that all packages are
installed into separate directories and the actual directory tree is
then constructed via symlinks.

This interacts badly with the way LyX currently detects files in the
TeX setup, because TeXFiles.py does not follow symlinks. Therefore,
almost nothing is found when using LyX together with Nix’ LaTeX.

Patch from Michael Roitzsch.

# bibtex style files -> option bst

#
# bib, bbx and cbx support added by Juergen Spitzmueller (v0.4)

# translated to python by Bo Peng, so that the script only
