Call lseek(0, SEEK_CUR) unconditionally in runsc fsgofer's Readdir(offset=0).
9P2000.L is silent as to how readdir RPCs interact with directory mutation. The
most performant option is for Treaddir with offset=0 to restart iteration,
avoiding needing to walk+open+clunk a new directory fid between invocations of
getdents64(2), and the VFS2 gofer client assumes this is the case. Make this
actually true for the runsc fsgofer.
Fixes #3344, #3345, #3355
