rename, renameat, renameatu: Fix test failures on Android/Termux

[Bruno Haible]

Similar tests failures are seen on Android 11 with Termux:

FAIL: test-rename
=================

link: Permission denied
FAIL test-rename (exit status: 1)

FAIL: test-renameat
===================

link: Permission denied
../../gltests/test-rename.h:80: assertion 'mkdir (BASE "dir", 0700) == 0' failed
Aborted
FAIL test-renameat (exit status: 134)

FAIL: test-renameatu
====================

link: Permission denied
../../gltests/test-rename.h:80: assertion 'mkdir (BASE "dir", 0700) == 0' failed
Aborted
FAIL test-renameatu (exit status: 134)

The workaround is the same: Mark these tests as SKIPped.
