They were introduced back when std_detect was a standalone crate published to crates.io. The motivation for std_detect_dlsym_getauxval was to allow using getauxval without dlopen when statically linking musl, which we now unconditionally do for musl. And for std_detect_file_io to allow no_std usage, which std_detect now supports even with that feature enabled as it directly uses libc. This also prevents accidentally disabling runtime feature detection when using cargo build -Zbuild-std -Zbuild-std-features=
It is no longer a part of the stdarch repo and the rest is not necessary anymore due to no longer publishing to crates.io.

Remove std_detect_file_io and std_detect_dlsym_getauxval features They were introduced back when std_detect was a standalone crate published to crates.io. The [motivation](rust-lang/stdarch#655) for `std_detect_dlsym_getauxval` was to allow using `getauxval` without `dlopen` when statically linking musl, which we now unconditionally do for musl. And for `std_detect_file_io` to allow `no_std` usage, which std_detect now supports even with that feature enabled as it directly uses libc. This also prevents accidentally disabling runtime feature detection when using `cargo build -Zbuild-std -Zbuild-std-features=`
