Add MODULE_INIT_COMPRESSED_FILE definition

[sinkingpoint]

This adds in the definition for MODULE_INIT_COMPRESSED_FILE so that we can use it in the init_module class of functions to load compressed modules

Fixes #3781

It looks like there may be some platforms where this isn't available. Could you please take a look at the failures on the latest CI?

It looks like MOD_INIT_COMPRESSED_FILE was added in Linux 5.17. My guess is that the arm test is failing because it's the first test that runs on a version of Linux older than that.

@sinkingpoint could you rebase to get a fresh run of tests? This probably just needs something added in libc-test/build.rs to account for the kernel versions this is available on, as mentioned by @nathaniel-bennett

I pushed your branch with a rebase just to get fresh CI. Seems like this will need to be disabled on at least a few platforms.
