installer: ignore light.exe internal error

Wix Toolset introduced an issue beginning with the v3.14.0.3827 release.
When linking merge module, the light.exe displays an internal error:

```
WixLink:
  "C:\Program Files (x86)\WiX Toolset v3.14\bin\light.exe"  -nologo -b o
  utput_dir="..\amd64\Release" -spdb -sw1076 -sw1079 -out "..\dist\wintu
  n-amd64-0.8.msm" "..\amd64\Release\installer-intermediate\installer.wi
  xobj"

light.exe : error LGHT0217: Error executing ICE action 'ICE103'. The mos
t common cause of this kind of ICE failure is an incorrectly registered
scripting engine. See http://wixtoolset.org/documentation/error217/ for
details and how to solve this problem. The following string format was n
ot expected by the external UI message logger: "There is a problem with
this Windows Installer package. A DLL required for this install to compl
ete could not be run. Contact your support personnel or package vendor.
 ". [C:\Users\Simon\Projekti\wintun\installer\installer.vcxproj]
  The command ""C:\Program Files (x86)\WiX Toolset v3.14\bin\light.exe"
   -nologo -b output_dir="..\amd64\Release" -spdb -sw1076 -sw1079 -out "
  ..\dist\wintun-amd64-0.8.msm" "..\amd64\Release\installer-intermediate
  \installer.wixobj"" exited with code 217.
```

This error is not a direct consequence of anything being wrong in our
source code. Fortunately, the utility still produces identical MSM file
as previous WiX Toolset versions do. Unfortunately, it exits with code
217.

However, we need recent v3.14 for ARM64 support.

I know this is a huge issue for our build system, masking out any other
potential true error, but the light.exe exit code has been temporarily
ignored.
