tracing: Add alignment to syscall metadata declarations

For some reason if we declare a static variable and then assign it
later, and the assignment contains a __attribute__((__aligned__(#))),
some versions of gcc will ignore it.

This caused the syscall meta data to not be compact in its section
and caused a kernel oops when the section was being read.

The fix for these versions of gcc seems to be to add the aligned
attribute to the declaration as well.

This fixes the BZ regression:
