gmain: Move doc comment for g_steal_fd() to be next to the code

Browse Source 
Nobody’s going to keep it up to date if it’s floating about in an
unrelated place, not next to the code.

/**
* g_steal_fd:
* @fd_ptr: (not optional) (inout): A pointer to a file descriptor
*
* Sets @fd_ptr to `-1`, returning the value that was there before.
*
* Conceptually, this transfers the ownership of the file descriptor
* from the referenced variable to the caller of the function (i.e.
* ‘steals’ the reference). This is very similar to [func@GLib.steal_pointer],
* but for file descriptors.
*
* On POSIX platforms, this function is async-signal safe
* (see [`signal(7)`](man:signal(7)) and
* [`signal-safety(7)`](man:signal-safety(7))), making it safe to call from a
* signal handler or a #GSpawnChildSetupFunc.
*
* This function preserves the value of `errno`.
*
* Returns: the value that @fd_ptr previously had
* Since: 2.70
