c36977f0b1 ELF: amd64-linux main programs use 2-step de-compressor 
The first $ARCH to move to 2-step de-compressor for ELF main programs.
De-compressor uses memfd_create to comply with strictest SELinux
settings (no PROT_WRITE on any PROT_EXEC page).
First step de-compressor always uses NRV2B to de-compress the second step,
and the second step can use a different de-compressor for each PT_LOAD.
