Avoid warnings about empty conditional statement bodies

Add extra {} braces around if/else statements which only
call SPICE_DEBUG to avoid:

../common/ssl_verify.c: In function 'verify_pubkey':
../common/ssl_verify.c:87:50: warning: suggest braces around empty body in an 'else' statement [-Wempty-body]
../common/ssl_verify.c: In function 'verify_hostname':
../common/ssl_verify.c:254:53: warning: suggest braces around empty body in an 'if' statement [-Wempty-body]
../common/ssl_verify.c: In function 'verify_subject':
../common/ssl_verify.c:381:41: warning: suggest braces around empty body in an 'else' statement [-Wempty-body]
