[LTP] proc01 failures with selinux disabled

[Kamalesh B. <kam...@li...>]

Hi Subrata,

	When running the testcases/kernel/fs/proc/proc01 testcase, the
/proc/self/*/attr/* read fails, if the selinux is not enabled. The 
function cap_getprocattr() is called when selinux is disabled, while 
reading the /proc/self/*/attr/* files and it returns -EINVAL,
whereas if the selinux is enabled the read passes because the selinux
equivalent selinux_getprocattr() is called.

proc01     12  FAIL  :  /proc/self/attr/sockcreate: read: Invalid argument
proc01     13  FAIL  :  readproc() failed with 12 errors.

This patch added the /proc/self/*/attr/* to know_issue array, these
arrary element could be called only when the read fails (when selinux is
disabled).
