third_party: update libcurl from 7.76.0 to 7.80.0

Changelog: https://curl.se/changes.html#7_80_0

- curl 7.78.0 has not metalink support, see blog post about it [1] and
pull request [2].
- libcurl build requires autotools, added required packages to .travis.mk

NOTE: Job release_asan_clang11 in continuous integration triggers memory
leak in Curl_resolv():
