[klibc] nfsmount: Fix alignment of packet structures
These structures should have alignment of exactly 4, since we want the
32-bit fields in them to have natural alignment but we don't want extra
padding that would violate the wire protocols.
This should be what happens by default, but for some reason it's
declared with the "packed" attribute. gcc is now warning about using
potentially misaligned pointers to its members.
Add the attribute "aligned(4)" so that it is definitely exactly 4-byte
aligned.
