Correctly fill siginfo for the signals delivered by linux tkill/tgkill.
It is required for async cancellation to work.
Fix PROC_LOCK leak in linux_tgkill when signal delivery attempt is made
to not linux process.
Do not call em_find(p, ...) with p unlocked.
Move common code for linux_tkill() and linux_tgkill() into
linux_do_tkill().
Change linux siginfo_t definition to match actual linux one. Extend
uid fields to 4 bytes from 2. The extension does not change structure
layout and is binary compatible with previous definition, because i386
is little endian, and each uid field has 2 byte padding after it.
