perf tools: Fix statfs.f_type data type mismatch build error with uclibc

ARC Linux uses the no legacy syscalls abi and corresponding uClibc headers statfs defines f_type to be U32 which causes perf build breakage http://git.uclibc.org/uClibc/tree/libc/sysdeps/linux/common-generic/bits/statfs.h ----------->8--------------- CC fs/fs.o fs/fs.c: In function 'fs__valid_mount': fs/fs.c:82:24: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare] else if (st_fs.f_type != magic) ^ cc1: all warnings being treated as errors ----------->8---------------
