[CRIU] [PATCHv4 7/8] criu/proc: Define BUF_SIZE without PAGE_SIZE dependency

[Dmitry Safonov]

PAGE_SIZE will be a variable value on platforms where it can be
different due to large pages.
And looks like (c) there is no reason for BUF_SIZE == PAGE_SIZE,
so let's keep it as it was, rather than complicating it with dynamic
allocation for the buffer.
