Since crypto/ebcdic.{c,h} are not present in BoringSSL, remove the #ifdefs
Changes were made by running
find . -type f -name *.c | xargs unifdef -m -U CHARSET_EBCDIC
find . -type f -name *.h | xargs unifdef -m -U CHARSET_EBCDIC
using unifdef 2.10.
An additional two ifdefs (CHARSET_EBCDIC_not) were removed manually.
