pytest: fixes for recent python, add FTP tests

Fixes:
- in uds tests, abort also silently on os errors
- be conservative on the h3 goaway duration
- detect curl debug build and use in checks
- fix caddy version check for slight difference under linux
- set caddy default path fitting for linux
- fix deprecation warnings in valid time checks

FTP tests:
- add '--with-test-vsftpd=path' to configure
- use vsftpd default path suitable for linux
- add test_30 with plain FTP tests
- add test_31 with --ssl-reqd FTP tests
- add vsftpd to linux GHA for pytest workflows

rustls: fix handshake done handling

- rustls report it has finished the TLS handshake *before*
all relevant data has been sent off, e.g. it FINISHED message
- On connections the send data immediately, this was never noticed
as the FINISHED in rustls buffers was send with the app data
- On passive FTP connections, curl does not send any data after
the handshake, leaving FINISHED unsent and the server never
responded as it was waiting on this.

cmake: initialize `BUILD_TESTING` before first use

Before this patch `BUILD_TESTING` was used once, then initialized, then
used again. This caused the `curlu` library not being built when relying
on an implicit `BUILD_TESTING=ON` setting, and ending up with a link
error when building the `testdeps` target.

It did not cause issues when `BUILD_TESTING` was explicitly set.

Move the initialization before the first use to fix it.
