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.
Closes#14183
The threee tags `<name>`, `</name>` and `<command>` were frequently used
with a leading space that this removes. The reason this habbit is so
widespread in testcases is probably that they have been copy and pasted.
Hence, fixing them all now might curb this practice from now on.
Closes#12028
Commit 46d45ea3a incorrectly hardcoded the User-Agent in the test
output file which breaks when curlver is updated. Shift to using
the %VERSION macro instead.
Closes: #8856
