Need a workaround to build on Ubuntu-18.04 due to "gettid"

To build on Ubuntu-18.04 I need to add this:

-------------------- bootstrap/stage0/runtime/AK/Format.cpp --------------------
index 43b125cb..58ac662a 100644
@@ -34,6 +34,11 @@
 #    include <AK/StringFloatingPointConversions.h>

+#include <sys/syscall.h>
+#define gettid() syscall(SYS_gettid)
+#endif

 namespace AK {
 
 namespace {

Jakt's "copy" of AK is strictly downstream from Serenity's, please make an issue/PR there instead.
