libstdc++: Do not include <system_error> in concurrency headers
The <condition_variable>, <mutex>, and <shared_mutex> headers use
std::errc constants, but don't use std::system_error itself. They only
use the __throw_system_error(int) function, which is defined in
<bits/functexcept.h>.
By including the header for the errc constants instead of the whole of
<system_error> we avoid depending on the whole std::string definition.
libstdc++-v3/ChangeLog:
* include/bits/std_mutex.h: Remove <system_error> include.
* include/std/condition_variable: Add <bits/error_constants.h>
include.
* include/std/mutex: Likewise.
* include/std/shared_mutex: Likewise.
