fix set ipv4 netmask failed

Before `createIfAddr`, we accept the address is nullopt when set the
ipv4 netmask,

so, if the address is not null, check the address is `0.0.0.0`,
if null, use the `ifaddr->address`.

Tested:
1. Set netmask.
~# ipmitool lan set 1 netmask 255.255.255.0

2. Check the netmask.
~# ipmitool lan print 1 | grep -i sub
Subnet Mask             : 255.255.255.0

Compile ipmid with default options:

meson builddir
ninja -C builddir

Compile ipmid with yocto defaults:

meson builddir -Dbuildtype=minsize -Db_lto=true -Dtests=disabled
ninja -C builddir

If any of the dependencies are not found on the host system during configuration, meson automatically gets them via its wrap dependencies mentioned in ipmid/subprojects.

Enable/Disable meson wrap feature

meson builddir -Dwrap_mode=nofallback
ninja -C builddir

Enable debug traces

meson builddir -Dbuildtype=debug
ninja -C builddir

Generate test coverage report:

meson builddir -Db_coverage=true -Dtests=enabled
ninja -C builddir test
ninja -C builddir coverage
