Fix gcc-9.3 compile errors (-Werror=format-security)

[ggreif]

Fixes a bunch of error when compiling with gcc-9.3, like below:

/home/ggreif/llvm-project/lldb/source/Core/Module.cpp: In member function ‘void lldb_private::Module::FindTypes_Impl(lldb_private::ConstString, const lldb_private::CompilerDeclContext&, size_t, llvm::DenseSet<lldb_private::SymbolFile*>&, lldb_private::TypeMap&)’:
/home/ggreif/llvm-project/lldb/source/Core/Module.cpp:930:52: error: format not a string literal and no format arguments [-Werror=format-security]
  930 |   Timer scoped_timer(func_cat, LLVM_PRETTY_FUNCTION);
      |                                                    ^

      |                                                          ^

These are unsafe uses of format strings, worth fixing.
