[PATCH] libtracefs: use mode with open()

[Sudip Mukherjee <sudipm.mukherjee@xxxxxxxxx>]

If -D_FORTIFY_SOURCE=2 is mentioned as a buildflag then the build fails
with the error:
In function ‘open’,
    inlined from ‘copy_trace_file’ at tracefs-utest.c:1032:10:
error: call to ‘__open_missing_mode’ declared with attribute error:
  open with O_CREAT or O_TMPFILE in second argument needs 3 arguments

Mention the permission with open() when O_CREAT is mentioned.
