[release-branch.go1.22] runtime: on AIX, fix call to _cgo_sys_thread_create in _rt0_ppc64_aix_lib
The AIX ABI requires allocating parameter save space when calling
a function, even if the arguments are passed via registers.
gcc sometimes uses this space. In the case of the cgo c-archive
tests, it clobbered the storage space of argc/argv which prevented
the test program from running the expected test.
Fixes #68972
