perf symbol: Pass is_kallsyms to symbols__fixup_end()

commit 838425f2defe5262906b698752d28fd2fca1aac2 upstream.

The symbol fixup is necessary for symbols in kallsyms since they don't
have size info.  So we use the next symbol's address to calculate the
size.  Now it's also used for user binaries because sometimes they miss
size for hand-written asm functions.

There's a arch-specific function to handle kallsyms differently but
currently it cannot distinguish kallsyms from others.  Pass this
information explicitly to handle it properly.  Note that those arch
functions will be moved to the generic function so I didn't added it to
the arch-functions.
