Sam Ravnborg 07fca0e57f tracing: Properly align linker defined symbols
We define a number of symbols in the linker scipt like this:

    __start_syscalls_metadata = .;
    *(__syscalls_metadata)

But we do not know the alignment of "." when we assign
the __start_syscalls_metadata symbol.
gcc started to uses bigger alignment for structs (32 bytes),
so we saw situations where the linker due to alignment
constraints increased the value of "." after the symbol assignment.

This resulted in boot fails.

Fix this by forcing a 32 byte alignment of "." before the
assignment.

This patch introduces the forced alignment for
ftrace_events and syscalls_metadata.
It may be required in more places.
