>Description:
The /usr/pkgsrc/mk/bulk/mksandbox script does not mount the main system's 
postfix directories to the sandbox and thus the bulk build script can't send 
email from sandbox through the postfix.

Attached patch adds the following to the mksandbox script:
Mount /var/spool/postfix read-only to the sandbox and then mount 
/var/spool/postfix/maildrop read-write to the sandbox. This allows sending the 
final email report through the postfix.
