Revert "all: build: fix sdkPath for relative @src.file / fix autocompletion with ZLS / IDEs (#661)"

Browse source 
This reverts commit a1fe671db8.

Lue suggested reverting #661 because ZLS worked around the issue of @src
being relative in that environment: https://github.com/zigtools/zls/pull/898

This is not a perfect solution (what zls did seems to be a workaround), but
is good enough for us until Zig gets an official package manager.
