util: Correctly handle short writes in m5 (read|exec)file

The m5 tool has subcommands that writes a file to the simulated file
system. The implementation of this command currently doesn't check the
return value from write, which leads to compiler warnings and
potentially incorrect behavior. Add the necessary checks.
