[LTP] [PATCH v2] mem/hugetlb: use SAFE_SHMGET() in hugeshmget setup function.

[Samir <samir@linux.ibm.com>]

I updated hugeshmget02.c and hugeshmget05.c to use SAFE_SHMGET() and configured the setup paths
so that shared memory allocation succeeds as expected.

In hugeshmget03.c, I also simplified the tst_brk() message by removing the unnecessary
__func__ usage and keeping a straightforward shmget() error message.
