Build errors with g++ 11

[Thomas Horsley]

Apparently latest C++ includes a std::byte and the way veracrypt source uses byte it now conflicts with the typedef in the veracrypt source.

Ths is gcc version 11.0.1 20210324 (Red Hat 11.0.1-0) (GCC) on fedora 34 with veracrypt 1.24 update 7 source

[Thomas Horsley]

I got it to build by hacking up a little perl script and running it over every source file to change "byte" to "BITE" (except Crypto/cpu.c where there is inline assembly with a .byte directive).
