Increase the /proc/stat scanner tokens size from the default of 65k to
1024k. This allows for scanning of large `intr` lines with > 65k
columns.
* Increase the scanner buffer from the default 4kB to 8kB bytes at a time.

Fixes: #546

This allows users to specify the "nostatfs" build tag to disable this feature if needed.

In our case, we are using Tamago (https://github.com/usbarmory/tamago), which does not support syscall.Statfs. Without this change attempting to build returns 'undefined: syscall.Statfs' and 'undefined: syscall.Statfs_t'. With this change, we can build successfully build our tamago executables provided that "nostatfs" is added to the build tags.

This option seems preferable to adding "tamago" as a build tag here, and will scale to other use cases too.
