perf tools: Update types definitions for Android

Some type definitions are missing from Android or are already defined in
bionic and lead to redefinition errors.

Android defines in types.h __le32. Since perf is wrapping <linux/types.h> with a
local version, we need to define this constant in the local version too.
Error in Android:
In file included from bionic/libc/include/unistd.h:36:0,
                 from external/perf/tools/perf/util/util.h:46,
                 from external/perf/tools/perf/util/cache.h:5,
                 from external/perf/tools/perf/util/abspath.c:1:
bionic/libc/kernel/common/linux/capability.h:60:2:
error: unknown type name '__le32'

roundup() definition is missing:
util/symbol.c: In function 'symbols__fixup_end':
util/symbol.c:106: warning: implicit declaration of function 'roundup'
util/symbol.c:106: warning: nested extern declaration of 'roundup'

__force macro defined in perf is also defined in libc which leads to
redefinition errors. In order to avoid these, we guard these definition
with
