sysvipc: Fix tst-sysvshm-linux on x32
The Linux shminfo fields are '__syscall_ulong_t' (which is 64-bit for x32). This patch fixes the test to compare againt the correct type and to only clamp the value if '__syscall_ulong_t' is the same size of 'unsigned long int'. Checked on x86_64-linux-gnu-x32.
