curl: upgrade to release 7.65.0

Fixes CVE-2019-5435. It looks like this is not a problem on 32-bit
Windows because fortunately we don't use /LARGEADDRESSAWARE flag
to set IMAGE_FILE_LARGE_ADDRESS_AWARE... but on 32-bit Linux
the user-space VM is 3GB so an exploit might be possible.

Apparently there's no code in LO that uses the CURLU_URLENCODE flag.

The other one, CVE-2019-5436, doesn't matter because we disable tftp.
