[PATCH] kselftest/pidfd: Make all test functions return int

[Ivan Pravdin]

The pidfd_test suite currently defines six test functions,
four of which return an int, while the remaining
two return void. This is inconsistent.

To address this, convert the two void-returning test
functions to return int, bringing them in line with
the rest. For now, the functions always return 0.
