linprocfs: use %z for size_t arguments

(rightly) that these are size_t and need a %z modifier.

According to the Linux sources the kernel exposes a proces virtual

The fix is based on a fernape@ analysis.

linprocfs: Skip printing of the guard page in the /proc/self/maps

To calculate the base (lowest addressable) address of the stack of the
initial thread glibc parses /proc/self/maps.
In fact, the base address is calculated as 'to' value of stack entry of the
/proc/self/maps - stack size limit (if the stack grows down).
The base address should fit in between preceding entry and stack entry of
the /proc/self/maps.
In FreeBSD, since 19bd0d9 (Implement address space guards), we actually
have two mappings for the stack region. The first one is the no-access
mapping for the region the stack can grow into (guard page), and the
second - initial stack region with size sgrowsiz.
The first mapping confuses Glibc, in the end which is improperly
calculate stack size and the base address.
