Extend nm_utils_file_set_contents to be able to optionally set the last
access + last modification times on the file being created, in addition
to the mode.
This reverts commit 389575a6b1.
When the command line contains BOOTIF and there is another ip=
argument specifying an interface name, we can follow 2 approaches:
a) BOOTIF creates a new distinct connection with DHCP
(the behaviour before the commit)
b) the connection generated for ip= will be also be bound to the
BOOTIF MAC (the behavior introduced by the commit)
Restore a) because we can't be sure that the MAC address refers to the
same interface. In that case it's preferable to generate a different
connection.

Ignore a rd.znet argument without subchannels. When using net.ifnames
(the default), subchannels are used to build the interface name, which
is required to match the right connection.
With net.ifnames=0 the interface name is build using a prefix and a
global counter and therefore in theory it is possible to omit
subchannels. However, without subchannels there won't be a udev rule
that renames the interface and so it can't work.

The code did:
key = g_strndup(tmp, val - tmp);
val[0] = '\0';
That is pointless. If we strndup the key, we don't need to truncate
the string at the '='. It might be nicer not to mutate the input string,
however, the entire code with "argument" parsing is about mutating the
input string, so that is something we apparently are fine with.
As such, don't clone the string anymore.
