[OE-core] [PATCH 1/1] attr: make ptest pass when selinux enabled

[kai.kang at windriver.com]

From: Kai Kang <kai.kang at windriver.com>

When selinux is enabled, a file has a default attribute
"security.selinux" and the output of getfattr shows:

  # file: here
  security.selinux="system_u:object_r:lib_t:s0"

That always causes more output of command getfattr than expected.
Filter out selinux related attribute info, and if the file has only
selinux attribute info, remove its whole output.
