[LTP] [PATCH 1/2] proc01: fix selinux attributes without libselinux-dev

[Krzysztof Kozlowski]

SELinux can be enabled on the system which does not have development
selinux libraries.  Such case was already done for Smack and Apparmor
where we unconditionally accept their attribute failures.  Do the same
for SELinux to fix failures like:

    proc01      1  TFAIL  :  proc01.c:404: read failed: /proc/self/task/29986/attr/selinux/current: errno=EINVAL(22): Invalid argument
    proc01      2  TFAIL  :  proc01.c:404: read failed: /proc/self/task/29986/attr/selinux/prev: errno=EINVAL(22): Invalid argument
    proc01      3  TFAIL  :  proc01.c:404: read failed: /proc/self/task/29986/attr/selinux/exec: errno=EINVAL(22): Invalid argument
    proc01      4  TFAIL  :  proc01.c:404: read failed: /proc/self/task/29986/attr/selinux/fscreate: errno=EINVAL(22): Invalid argument
    proc01      5  TFAIL  :  proc01.c:404: read failed: /proc/self/task/29986/attr/selinux/keycreate: errno=EINVAL(22): Invalid argument
    proc01      6  TFAIL  :  proc01.c:404: read failed: /proc/self/task/29986/attr/selinux/sockcreate: errno=EINVAL(22): Invalid argument
    ...
    proc01      7  TFAIL  :  proc01.c:404: read failed: /proc/self/attr/selinux/current: errno=EINVAL(22): Invalid argument
    proc01      8  TFAIL  :  proc01.c:404: read failed: /proc/self/attr/selinux/prev: errno=EINVAL(22): Invalid argument
    proc01      9  TFAIL  :  proc01.c:404: read failed: /proc/self/attr/selinux/exec: errno=EINVAL(22): Invalid argument
    proc01     10  TFAIL  :  proc01.c:404: read failed: /proc/self/attr/selinux/fscreate: errno=EINVAL(22): Invalid argument
    proc01     11  TFAIL  :  proc01.c:404: read failed: /proc/self/attr/selinux/keycreate: errno=EINVAL(22): Invalid argument
    proc01     12  TFAIL  :  proc01.c:404: read failed: /proc/self/attr/selinux/sockcreate: errno=EINVAL(22): Invalid argument
