[PATCH] Fix catchsegv

[Jakub Jelinek]

Hi!

$LIB in LD_PRELOAD=.../$LIB/libSegFault.so needs to be escaped
from shell.  Either of the following patches work, I'd say adding
single quotes is better in case of weirdo slibdir paths e.g. with
embedded spaces and other chars (but that will not handle
properly paths with embedded quotes).
