Make hg-fst-export.sh callable via a symbolic link

Browse Source 
Calling hg-fast-export.sh via a symlink used to fail because the
script would look for hg-fast-export.py in the symlink‘s
directory. This patch adds symlink resolution using greadlink with a
fallback to readlink in order to support MacOS. That way you can
safely add a symlink to hg-fast-export.sh somewhere in you PATH.
