[Lucid] SRU: nfsd4: permit read opens of executable-only files

SRU Justification


NFSv4 mount point does not allow binary files to run when permissions
are set to 111.


Upstream commit a043226bc140a2c1dde162246d68a67e5043e6b2.
Applies with minor conflicts (include file is in a different directory).

Mount a directory using nfsv4. Inside that directory place a binary with
---x--x--x permissions. Try to execute the binary. Without this patch it
will not execute.

This patch fixes this issue, but requires support from the nfs client as
well. The Lucid version of the client works as expected.
