Escape DEL char (ASCII 127 decimal) in SSIDs

Browse source 
While testing, I noticed that printf_encode() makes control characters
human-readable, with one exemption, the DEL character (ASCII 127).
Assuming this exemption was unintentional, make it appear as an escaped
\x7f instead of a literal DEL character in the output.
