cmd/internal/ld, runtime: halve tlsoffset on ELF/intel
For OSes that use elf on intel, 2*Ptrsize bytes are reserved for TLS.
But only one pointer (g) has been stored in the TLS for a while now.
So we can set it to just Ptrsize, which happily matches what happens
when externally linking.
Fixes #9913
