http_client: Fix GitHub download unpack failures on some filesystems (#53286)

Disable mtime preservation when unpacking tar archives, as some
filesystems error when asked to set it. Follows how
[cargo](1ad92f77a8/src/cargo/ops/cargo_package/verify.rs (L59)
) and
[uv](0da0cd8b43/crates/uv-extract/src/stream.rs (L658))
handle it.
