Fix capitalization in video profiles causing invalid transcodes

[nielsvanvelzen]

After merging #3932 some videos stopped playing for me with this error:

[hevc_nvenc @ 0000023043dc9f40] [Eval @ 00000039cbdfe4b0] Undefined constant or missing '(' in 'Main'

Conversion failed!

Turns out, our server doesn't sanitize shit and de nvenc encoder expects fully lowercase profiles. The server itself compares those strings everywhere ignoring casing though. Ideally this must be fixed serverside too.

I had checked what the server was taking, and saw it was ignoring case. And the profiles were already a mixture up of lower and uppercase entries. All being the same I decided that uppercase looked better, so I went with that. Go figure.

Yeah I also wouldn't expect it to cause problems, but when it did I checked the other clients and all send the profiles in lowercase.
