unix: fix or skip failing tests on android and iOS

The mkfifo syscall is disallowed on android and iOS. sched_setaffinity
is disallowed on android. Skip all tests which use them.

/usr/bin does not exist on android. Use /system/bin in TestGetwd
instead, like TestChdirAndGetwd in the os package.

Like linux, android does not support Fchmodat with flags != 0. Adjust
TestFchmodat accordingly.

TestDevices might stat some device files which are not accessible, skip
those.

iOS cannot exec subprocesses, thus skip TestPassFD.

Fixes golang/go#25535
