Subject: [PATCH] selftests/kcmp: Remove unused open mode

Android bionic warns that open modes are ignored if O_CREAT or O_TMPFILE
aren't specified.  The permissions for the file are set above:

	fd1 = open(kpath, O_RDWR | O_CREAT | O_TRUNC, 0644);

Fixes: d97b46a64674 ("syscalls, x86: add __NR_kcmp syscall")
