--------------------------------

commit a7e793a8 upstream.

non-regular file needs to be compiled and then copied to the output
directory. Remove it from TEST_PROGS and add it to TEST_GEN_PROGS. This
removes error thrown by rsync when non-regular object isn't found:

rsync: [sender] link_stat "/linux/tools/testing/selftests/exec/non-regular" failed: No such file or directory (2)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1333) [sender=3.2.3]
