Add the full module path name to the kld_file_stat structure

for kldstat(2).

This allows libdtrace to determine the exact file from which
a kernel module was loaded without having to guess.

The kldstat(2) API is versioned with the size of the
kld_file_stat structure, so this change creates version 2.

Add the pathname to the verbose output of kldstat(8) too.
