[OE-core] [PATCH 3/3] msmtp: add link file /usr/lib/sendmail

[Kai Kang]

Link file /usr/lib/sendmail points to /usr/sbin/sendmail is required by
LSB core test according to Linux FHS: "For historical reasons,
/usr/lib/sendmail must be a symbolic link to /usr/sbin/sendmail if the
latter exists."

Create the link file /usr/lib/sendmail if it doesn't exist.
