[folly] Remove vcpkg_fail_port_install. (#22745)

* [folly] Remove vcpkg_fail_port_install.

vcpkg.json was missing the uwp skip but otherwise agreed. There is no ci.baseline.txt impact because:

     Error: libevent[core] is only supported on '!uwp'

In support of https://github.com/microsoft/vcpkg/pull/21502

* Give up trying to prove that the support expression is correct and just follow what portfile.cmake says.

* Fix brain fart @JackBoosY found.
