patch for usr.bin/man.sh to check null filename

When a manpage contains a .so link to a second manpage, man(1) displays first file in current directory

The function exists() in man.sh uses file globbing to check if file exists. When called with a null filename, such as when redirecting .so link to new manpage file, globbing returns the name of the first file in the current directory.

sean@clifden:~ % zgrep -e "^\.so" /usr/local/share/man/man1/doveadm-backup*
/usr/local/share/man/man1/doveadm-backup.1.gz:.so man1/doveadm-sync.1

sean@clifden:~ % man -w doveadm-backup
a-file-in-directory (source: "/usr/local/share/man/man1/doveadm-sync.1.gz")
