Subject: Fixing segfault crash in x86_64 get_size testcase

getsize_x86_64 testcase is crashing with segfault
when trying to access the stack pointer.

Compile the testcase with -mstackrealign option to
realign the runtime stack so that segfault is
avoided when accessing the stack pointer.

Bug: 184920505
Signed-off-by: ahs <amrita.h.s@intel.com>
Test: run vts -m vts_linux_kselftest_x86_64 -t size_get_size_x86_64
