[PATCH] selftests/exec: Fix build

[Joerg Vehlow <lkml@jv-coder.de>]

From: Joerg Vehlow <joerg.vehlow@aox-tech.de>

This fixes
make: *** No rule to make target 'tools/testing/selftests/exec/pipe', needed by 'all'. Stop.

Targets defined in TEST_DEN_FILES must exist as targets in the makefile,
but pipe is only created by the test at runtime, so it should be cleaned only.

Fixes: 61016db15b8e ("selftests/exec: Verify execve of non-regular files fail")
