[Buildroot] [git commit branch/2017.05.x] linux: fix name of config variable

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=256f3f71484fc4bc15a4a7500384cfd2bd3a8c38
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.05.x

In 4c10eedc1 (systemd: enable required kernel features), we added
setting a few required kernel features to ensure systemd works.

However, there was a typo for one of the variables: CONFIG_TMPFS_XATTR
was written as CONFIG_TMPFS_POSIX_XATTR, which does not exist (and never
ever existed, at least not since 2.6.12)...
