libpciaccess: Do not use 64bit functions for largefile support

Using -D_FILE_OFFSET_BITS=64 already makes the normal function behave
like 64bit variants. Moreover it makes them portable across libc

+Subject: [PATCH] linux_sysfs: Use pwrite/pread instead of 64bit versions
+
+pread64/pwrite64 are aliased to pread/pwrite when largefile support is
+enabled e.g. using _FILE_OFFSET_BITS=64 macro
