Title: Add lttng 2.2.0 bbappend with ARM syscalls instrumentation patch

Bring up the commit from lttng master branch to version 2.2.0.
This patch updates ARM syscalls tracepoints to kernel version 3.4.

Although the kernel version, served by this patch, is less, than our versions, it's more preferable, than even previously used instrumentation for 3.5.6, because:
- this patch is from official upstream master branch, so future updates to later lttng versions will be smoother;
- the set of syscalls in 3.5 is almost the same as in 3.4 (just minor differences in argument names and types), so this patch will work for 3.5 too;
- this 3.4 instrumentation supports even more syscalls than previous "unofficial" 3.5 one (probably some syscalls were somehow masked while automatic list extraction last time).

Kernel version 3.8 has just one additional syscall, comparing to 3.5, so this instrumentation will work sufficiently good for 3.8 too (although that additional syscall will be traced as unknown).
