BUILD: sock_unix: fix build issue with isdigit()

Browse Source 
Commit 0d06df6 ("MINOR: sock: introduce sock_inet and sock_unix")
made use of isdigit() on the UNIX socket path without casting the
value to unsigned char, breaking the build on cygwin and possibly
other platforms. No backport is needed.
