#2465 Two fixes for sfcb-ps test script

[Dave Heller]

1. The "sfcb-ps" test script identifies SFCB processes by grepping through ps output for entries with 'sfcbd'. This is not ideal but is fast and simple. The detection is improved slightly by appending the regex boundary character '\b' to the search string. This avoids misidentification of processes that do not belong to SFCB but have these chars in their executable name.

2. In embedded environments, under heavy load with parallel client requests, there can be a transient period where a socket inode number is reported as zero in /proc/net/tcp or /proc/net/tcp6. This fouls sfcb-ps' detection of "Http Daemon" and "Http Request Handler" processes and causes other SFCB processes to be misidentifed as one of these. The patch is to discard any inode with value of 0.
