[yocto] [yocto-autobuilder][PATCH] SendQAEmail.py: use sendmail instead of mail to send QA email

[Bill Randle]

When sending QA emails, the autobuilder uses the 'mail' command (typically
installed as /usr/bin/mail or /bin/mail). However, most distributions do not
install this program by default. They generally always install the 'sendmail'
program, though, so use 'sendmail' as the mail agent, rather than 'mail'.
