gitlab-ci: Fix llvm-symbolizer

Browse Source 
Newer versions of llvm-symbolizer require libxml2 themselves. Running
a test program with LD_LIBRARY_PATH set to .libs makes llvm-symbolizer
pick up the tested development version of libxml2 which breaks
completely if the build is instrumented with ASan. Add a wrapper script
that invokes llvm-symbolizer with an empty LD_LIBRARY_PATH.
