mem: Make the File return io.ErrUnexpectedEOF
Instead of panic when reading beyond its borders.

This is in line with how the OS File works.

Jamie Wilkinson 52e4a6cfac Fixes a pass-by-value error in FileData.Name()
Fixes a pass-by-value error in FileData.Name() which causes the mutex to be copied, and use that method to retrieve the name of the file from a mem.File.  This really fixes the data race that motivated PR #95. (#96)

I can't explain why moving the lock improves the situation, nor why calling through the accessor Name() instead of locking and reading f.fileData.name is not the same, but go vet indicates that the mutex in fileData was being copied, not preserved.

The reproducing test case upstream is:
check out github.com/google/mtail
make install_deps
go test -race -timeout 1m -v -run TestProcessEvents --count=10000 ./vm

Prior to this change, the test reports a data race 3 times out of 10000, after, 0 times consistently.
