mtab: fix test for a link to a location in /proc
/etc/mtab can be a link to a file in /proc. If it is, we should not attempt to update /etc/mtab. The original test used "! -w" as part of the test. This does not work since everything is writeable by root. Thanks to Robin Johnson for the suggestion of using readlink -f and the regular expression.
