build: Add -trimpath compiler option (#6904)

Browse Source 
Quoting the manual:

    -trimpath
      remove all file system paths from the resulting executable.
      Instead of absolute file system paths, the recorded file names
      will begin with either "go" (for the standard library),
      or a module path@version (when using modules),
      or a plain import path (when using GOPATH).

That is, when we panic, instead of:

    goroutine 1 [running]:
    main.main()
        /Users/jb/dev/syncthing/syncthing/cmd/syncthing/main.go:272 +0x116

we get:

    goroutine 1 [running]:
    main.main()
        github.com/syncthing/syncthing@/cmd/syncthing/main.go:272 +0x116

(Module path and file path within module.)
