linux-user: Simplify host <-> target errno conversion using macros
Convert the host_to_target_errno_table[] array to a switch
case to allow compiler optimizations (such noticing the identity
function when host and guest errnos match). Extract the errnos
list as to a new includible unit, using a generic macro. Remove
the code related to target_to_host_errno_table[] initialization.
