1) use devname() instead of searching /dev for the dump device
2) use fopen() instead of open() so we don't need to differentiate
between compressing and not compressing when writing the core
file or the kernel (zopen() returns a FILE *, so we just use
fwrite() in both cases)
There should be no functional changes.
