test: fix test compilation on rawhide

Browse Source 
The latest glibc has redefined SIGSTKSZ as 'sysconf (_SC_SIGSTKSZ)' and
this breaks a static char[] definition.

Hardcoding TESTSIGSTKSZ to 16384 in the test. This fixes:

 sigaltstack.c:17:13: error: variably modified 'stack_thread' at file scope
   17 | static char stack_thread[SIGSTKSZ + TEST_MSG_BUFFER_SIZE] __stack_aligned__;
      |             ^~~~~~~~~~~~
sigaltstack.c:18:13: error: variably modified 'stack_main' at file scope
   18 | static char stack_main[SIGSTKSZ + TEST_MSG_BUFFER_SIZE] __stack_aligned__;
      |             ^~~~~~~~~~
