yushuailong d0e6183d1a libs/libc/dirent: preserve errno on readdir() end-of-directory ...

readdir() returned NULL at end-of-directory without ensuring errno was
clean.  POSIX requires errno to be unchanged at EOF, but the underlying
read() path may leave a stale errno value.  Callers that follow the
POSIX idiom (set errno to 0 before the call, test it after a NULL
return), such as readdir_r() and scandir(), then misread this as a
readdir() failure.

Save errno on entry and restore it on the end-of-directory return so
that EOF no longer reports a spurious error, while genuine errors
(read() returning a negative value) still propagate.
