Add a check on these calls to skip the test if we receive EINVAL.

The Bionic version of pthread_create used on Android calls the prctl function to give the stack and thread local storage a useful name. This will cause the KILL_THREAD test to fail as it will kill the thread as soon as it is created. change the test to use getpid instead of prctl.

Currently the user_notification_addfd test checks what the next expected file descriptor will be by incrementing a variable nextfd. This does not account for file descriptors that may already be open before the test is started and will cause the test to fail if any exist. Replace nextfd++ with a function get_next_fd which will check and return the next available file descriptor.

Additionally skip tests that depend on clone3 when it is not available (for example when building the seccomp selftests on an old arm image without clone3 headers). And improve error reporting for when nanosleep fails, as seen on arm32 since v5.15.
