Fixes to make the perl build reproducible:

a) Remove the \n from configure_attr.sh since it gets quoted differently depending on
   whether the shell is bash or dash which can cause the test result to be incorrect.
   Reported upstream: https://github.com/arsv/perl-cross/issues/87

b) Sort the order of the module lists from configure_mods.sh since otherwise
   the result isn't the same leading to makefile differences.
   Reported upstream: https://github.com/arsv/perl-cross/issues/88

c) Sort the Encode::Byte byte_t.fnm file output (and the makefile depends whilst 
   there for good measure)
   This needs to go to upstream perl (not done)

d) Use bash for perl-cross configure since otherwise trnl gets set to "\n" with bash
   and "" with dash
