syscall: use consistent message for ESTALE on Linux
For some reason the ESTALE error message differed on Linux systems.
On Linux strerror normally returns "Stale file handle" for ESTALE,
except possibly in the en_GB locale. The mkerrors.sh script sets
LC_ALL=C, so it should always produces "stale file handle".
However, for some reason, several targets use "stale NFS file handle"
instead.
Clean this up so that we use the same string on all Linux systems.
This is also consistent with golang.org/x/sys/unix.
Fixes #71309
