lapi/tls.h: Cleanup ifdefs

fe24196 added .supported_archs into clone10. Therefore there is no
need to keep architecture check also in lapi/tls.h.

Moreover "Unsupported architecture for TLS" was misleading as it looked
as a missing arch support in kernel, but it's our allocate_tls_area()
implementation which does support only 3 architectures.
