iotest 083 filters out debug messages from nbd, which are prefixed (and recognized) by __FILE__. However, the current filter (/^nbd\.c…/) is valid for in-tree builds only, as out-of-tree builds will have a path before that filename (e.g. "/tmp/qemu/nbd.c"). Fix this by adding .* before "nbd\.c". While working on this, also fix the regexes: '.' should be escaped and a single backslash is not enough for escaping when enclosed by double quotes.
