Move libstd's default feature to libtest

Browse Source 
This commit makes it so `std` no longer has a `default` feature, but
instead the `test` crate has a `default` feature doing the same thing.
The purpose of this commit is to allow Cargo's `-Zbuild-std` command,
which could customize the features of the standard library, to handle
the `default` feature for libstd. Currently Cargo's `-Zbuild-std`
support starts at libtests's manifest as the entry point to the std set
of crates.
