libio: Remove __libc_readline_unlocked

__nss_readline supersedes it.  This reverts part of commit
3f5e3f5d066dcffb80af48ae2cf35a01a85a8f10 ("libio: Implement
internal function __libc_readline_unlocked").  The internal
aliases __fseeko64 and __ftello64 are preserved because
they are needed by __nss_readline as well.
