pstree: Remove need for PATH_MAX

This commit removes the need for PATH_MAX in pstree.
It uses the fact that calling snprintf() with *str=NULL and size=0
returns the number of bytes needed for the string according to
POSIX.1-2001 and later (which is supported by all glibc versions
since 2.1, see snprintf(3)).
