[yocto] useradd.bbclass: Strip trailing ';' in cmd params

[Markus Volk]

Hello,

just to mention …

http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=553fa35147adb996d515c3d27f62555d9c969cd8 <http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=553fa35147adb996d515c3d27f62555d9c969cd8>

results in a do_rootfs loop here if an attached whitspace exists in USERADD_PARAM_${PN}

this fixes my problem:

regards,

Markus
