rseq_register_current_thread() either uses the glibc registered RSEQ region
or registers it's own region with the legacy size of 32 bytes.
That worked so far, but becomes a problem when the kernel implements a
distinction between legacy and performance optimized behavior based on the
registration size as that does not allow to test both modes with the self
test suite.
Add two arguments to the function. One to enforce that the registration is
not using libc provided mode and one to tell the registration to use the
legacy size and not the kernel advertised size.
Rename it and make the original one a inline wrapper which preserves the
existing behavior.
