Subject: [PATCH] posix: Fix attribute access mode on getcwd [BZ #27476]

There is a GNU extension that allows to call getcwd(NULL, >0). It is
described in the documentation, but also directly in the unistd.h
header, just above the declaration.

Therefore the attribute access mode added in commit 06febd8c6705
is not correct. Drop it.
