If tmux wasn't already running it would output an error but still work.
The new approach will suppress that since we're not concerned if it's
already running or not, just whether the desired session is.
Modified the live macOS args to support connecting to the HW-Diags
session remotely (more easily at least).
Not sure where the old reference to an "other" timezone came from.
Going to use the POSIX style esp. after finding the answer below.
Thankfully both options appear in macOS 10.11-10.15 in my testing.

This was not being pushed from a testing MacBook so I'm adding it all
at once. This is unfinished, still needs scripts to prep the working
macOS env from which the live env is built.
El Capitan code is likely to be dropped completely. Installing or
compiling dependencies in brew is problematic at this point.
NOTE: This was unintentionally squashed so some details were lost
* Major updates to build_linux to support the current archiso scripts
* Most customize_airootfs.sh code has been moved elsewhere
* Using static files or links where possible
* Generating other files as needed in build_linux
* Syslinux configuration has been simplified
* Dropped i3
* Dropped rxvt-unicode in favor of termite
* Font rendering broke one too many times
* Dropped NetworkManager in favor of iwd/systemd-networkd
* Replaces old write_registry_settings()
* Uses tuples to combine all parts of the values
* e.g. ('SampleValue', 'SampleData', 'SZ', '32)
* This will allow merging multiple setting groups together
* Should be more readable than the old method
