Update rav1e.cmd and docker/build.sh to use rav1e 0.4

[EwoutH]

Switches both rav1e.cmd and docker/build.sh to update from the rav1e 0.3 maintenance branch to the 0.4 maintenance branch.

Currently the CI is stuck on the following error:

/home/runner/work/libavif/libavif/src/codec_rav1e.c:6:10: fatal error: rav1e/rav1e.h: No such file or directory
    6 | #include "rav1e/rav1e.h"

I'm going to need a bit of help here, @joedrago can you make anything of it?

@lu-zero Could you confirm if rav1e.cmd now installs the c-compatible rav1e library correctly?

[lu-zero]

which version of cargo-c are you using ?

[EwoutH]

cargo-c v0.7.0+cargo-0.49 currently

[lu-zero]

you may include rav1e.h directly if pkg-config --cflags provides -I{includedir}/rav1e

[joedrago]

Your change to rav1e.cmd breaks the intent of the script. The goal of that script is to create a static, local build of the library, not install it into the system, and then require that the system has it available.

[joedrago]

If you want rav1e 0.4, please just change the version branches and leave the call to cbindgen alone.

Thanks for the reply, I tried that in the first commit of this PR, but unfortunately that run also fails.
libavif: compiled rav1e library is missing (in ext/rav1e/target/release),

[lu-zero]

The current cargo-c introduced {pkg}-uninstalled.pc to address this, but looks like it needs a fix, I'll look at it during the weekend.

[EwoutH]

Something I missed was that rav1e got stuck on this error: Error: CliError { error: Some(Permission denied (os error 13)), exit_code: 101 }

Which is probably a GitHub Actions problem. I will see if I can modify it to run with sudo privileges.
