dropbear: a fix for hang in dropbearkey, built for x32

This commit fixes runtime hang of 'dropbearkey' utility, built for a x32
target abi system. The hang was observed while generating ssh keys, with
this command:
  dropbearkey -t dss -f private

The issue is fixed by changing the code, where 'long' in x86_64 mode is
assumed as 64bit quantity. With the x32 abi, the processor is in x86_64
mode, but the 'long' is a 32bit quantity. Hence the fix uses 'long long'
instead of 'long' to define/access 64bit data variables.

Fixes bug:
[YOCTO #4496]
