setrlimit: Remove special handling for RLIMIT_STACK with a stack gap

Description

setrlimit: Remove special handling for RLIMIT_STACK with a stack gap

This will not be required with a forthcoming reimplementation of ASLR
stack randomization. Moreover, this change was not sufficient to enable
the use of a stack size limit smaller than the stack gap itself.
