Summary: Alignment errors when reading raw devices in Mac OS X

Initial Comment:
When running any SleuthKit tools against /dev/rdisk* in Mac OS X, you get
   kernel[0]: disk0: alignment error.
messages in syslog.  The tools work fine, despite the errors.

Tracking it down, it turns out to be the lseek(...,SEEK_END) in tsk3/img/raw.c that tries to determine the file's size.  There's already some Mac-specific code there to get the size of raw disk devices... the attached patch simply avoids the lseek() test if it's a character device on a Mac.
