ctdb-scripts: Fix stack dumping when debugging hung scripts
There are parentheses missing that stop the default pattern from
matching commands with trailing garbage (e.g. "exportfs.orig").
A careful check of POSIX (and running GNU sed with --posix) suggests
that "\|" isn't a supported way of specifying alternation in a regular
expression. Therefore, it is clearer to switch to extended regular
expressions so that this has a chance of being portable (even though
the point is to print /proc/<pid>/stack, which only works on Linux).
