Spi-hdlc-adapter: Copy the spi path name before passing to syslog() (#1135)

Browse Source 
This commit makes a change in `spi-hdlc-adapter` to copy the passed
in spi path (from the argv) in a max 64 char array before passing it
to `syslog()`. This ensures `syslog()` string argument has a limited
size.
