Use icon names from gnome-shell-extension-lockkeys

[mochaaP]

Support system icon theme settings.
Also, allow discrimination between enabled/disabled state

• ask upstream (1, 2) for scroll lock support / drop scroll lock support on our side
• use icons glyphs from upstream (1)
• switch to Adwaita's icon name for audio / microphone
• add option to discard gresource from binary / loading from external location (required for distribution packaging)
• fix error on cargo package

add option to discard gresource from binary / loading from external location (required for distribution packaging)

Why would this be necessary?

Why would this be necessary?

This mutates the source tree (usage of include_bytes) when invoking build.rs, which could cause some weird behavior while used alongside Fedora's Rust SRPM macros. (I forgot the exact details since it has been 3 months away from the original attempt, sorry 😅)

What would be an alternative?
