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. (cherry picked from commit 63a788f48a713f2081f200dd054df3e728b0e7c2)
