If the long option name ends with an equals sign (`=`), the argument is
the text following on its right side.
This makes the command line parser accept this common style in addition
to the existing way to accept option arguments more similar to how other
command line tools do.
Example: `curl --user-agent=curl-2000 https://example.com/`
Change a few existing tests to use this syntax: 206, 1333, 1335, 1442
Closes#17789
For all tests using -O that were previously relying on a debug build and
the CURL_TESTDIR environment variable, use the plain --output-dir option
instead so that they can run proper in non-debug builds.
Closes#15114
Some feature names used in tests had minor differences compared to
the well-known ones from `curl -V`. This patch syncs them to make test
results easier to grok.
