[compiler-rt] PR#39514 Support versioned llvm-symbolizer binaries

Some linux distributions produce versioned llvm-symbolizer binaries,
e.g. my llvm-11 installation puts the symbolizer binary at
/usr/bin/llvm-symbolizer-11.0.0 . However if you then try to run
a binary containing ASAN with
ASAN_SYMBOLIZER_PATH=..../llvm-symbolizer-FOO , it will fail on startup
with "isn't a known symbolizer".

Although it is possible to work around this by setting up symlinks,
that's kindof ugly - supporting versioned binaries is a nicer solution.
(There are now multiple stack overflow and blog posts talking about
 this exact issue :) .)
