ftrace: specify $alignment for sh architecture

Impact: extend scripts/recordmcount.pl with default alignment for SH

Set $alignment=2 for the sh architecture so that a ".align 2" directive
will be emitted for all __mcount_loc sections. Fix a whitspace error
while I'm here (converted spaces to tabs).
