Sweep: Replace x-hack in packages and lib/tools

[sweep-nightly[bot]]

x-hack is a shell/bash conditional using any letter (often 'x' thus the 'x-hack' name) followed by variable declaration ${var} and checking against the same letter followed by value such as:

# bash
[[ “x$var” == “xval” ]]

# POSIX shell
[ “x$var” = “xval” ]

This was done to ensure compatibility across different shells and systems many years ago, but today it's obsolete as the shells evolved enough to be more reliable.

That said the armbian codebase is still using them for some reason and it was agreed that these should be replaced so i want you to look through the codebase and fix all x-hacks.

Note that the declaration can also be written without quotes:

[ x$var = xval ]

Or even checking for a directory:

[ x$var = xval/ ]

• In packages/blobs/grub/09_linux_with_dtb.sh, replace all instances of the 'x-hack' with a more modern approach.
• In packages/bsp/nanopim4/nanopim4-pwm-fan.sh, replace all instances of the 'x-hack' with a more modern approach.
• In lib/tools/shellcheck.sh, replace all instances of the 'x-hack' with a more modern approach.
• In lib/functions/artifacts/artifact-armbian-bsp-cli.sh, replace all instances of the 'x-hack' with a more modern approach.
• In lib/functions/artifacts/artifact-firmware.sh, replace all instances of the 'x-hack' with a more modern approach.
