extrausers.bbclass: avoid infinite loop
Avoid infinite loop if the last record in EXTRA_USRES_PARAMS doesn't
end with a semicolon.
It's possible the the users will write configurations like below.
INHERIT += "extrausers"
EXTRA_USERS_PARAMS = "useradd tester; useradd developer"
In such situation, the do_rootfs task will enter an infinite loop.
An infinite loop is never acceptable.
This patch fixes the above problem.
