selftests/bpf: Fix open-coded gettid syscall in uprobe syscall tests

Commit 0e2fb011a0ba ("selftests/bpf: Clean up open-coded gettid syscall
invocations") addressed the issue that older libc may not have a gettid()
function call wrapper for the associated syscall.

The uprobe syscall tests got in from tip tree, using sys_gettid in there.
