Jay Satiro 12284e008b connect: fix wrong format specifier in connect error string 
0842175 (not in any release) used the wrong format specifier (long int)
for timediff_t. On an OS such as Windows libcurl's timediff_t (usually
64-bit) is bigger than long int (32-bit). In 32-bit Windows builds the
upper 32-bits of the timediff_t were erroneously then used by the next
format specifier. Usually since the timeout isn't larger than 32-bits
this would result in null as a pointer to the string with the reason for
the connection failing. On other OSes or maybe other compilers it could
probably result in garbage values (ie crash on deref).

Before:
Failed to connect to localhost port 12345 after 1201 ms: (nil)

After:
Failed to connect to localhost port 12345 after 1203 ms: Connection refused
