Update Italian translation. Closes: #721030
replace usage of potential dangerous mktemp with mkstemp

Avoid the warning "the use of `mktemp' is dangerous,
better use `mkstemp' or `mkdtemp'". It is not strictly necessary to
change the usage from a security point of view here, but mktemp is
also removed from the standard since POSIX.1-2008.

The mkostemp call returns a file descriptor the logic for
TemporaryFileName has been changed accordingly to get the same results.
The file permissions are corrected by using fchmod() as the default for
FileFd is 666 while mkstemp creates files with 600 by default.
use mkstemp instead of mkostemp in FileFd::Open()

FileFd currently supports no fileflags which would make sense to provide
via mkostemp, so we can just use mkstemp here which is a standard
function compared to glib extension mkostemp.

O_CREAT (Create) and O_TRUNC (Empty) are implied by O_EXCL, which is the
mode mkstemp uses by default. The file description is opened ReadWrite,
but that used to be the default for FileFd in the old times and not a
problem as the difference is needed by FileFd to decide in which way the
compressor pipeline needs to be created (if any).

Git-Dch: Ignore
old-style dpkg foreign architecture adding for tests

Looks like the travis service runs on Ubuntu in a version which has dpkg
with an earlier interface implementation, so lets try if we can't make
the framework work with this dpkg version as well.

Git-Dch: Ignore
configurable compression for testcases

Compressing files in 4 different styles eats test-time for no practical
gain if we don't test them explicitly, so default to just building 'gz'
compressed files as it is the simplest compression algorithm supported
