perf: Fix building warning on ARM 32

Commit 85c116a6cb91 ("perf callchain: Make get_srcline fall back to sym+offset")
introduces asprintf() call and matches '%ld' to a u64 argument, which is
incorrect on ARM:

   CC       /home/wn/util/srcline.o
 util/srcline.c: In function 'get_srcline':
 util/srcline.c:297:6: error: format '%ld' expects argument of type 'long int', but argument 4 has type 'u64' [-Werror=format]
 cc1: all warnings being treated as errors
 make[1]: *** [/home/wn/util/srcline.o] Error 1

In addition, all users of get_srcline() use u64 addr, and libbfd
also use 64 bit bfd_vma as address. This patch also fix
prototype of get_srcline() and addr2line() to use u64 addr
instead of unsigned long.
