Serge Pavlov 1d5fa4f88f [symbolizer] Change error message if module not found (recommit) ...

This is a recommit of 75f1f15881, reverted in 7a443b1c49, because
it caused compilation error in
compiler-rt/lib/sanitizer_common/symbolizer/sanitizer_symbolize.cpp.
The error was fixed by Kasimir Georgiev in de4c038c7b, but this
commit was reverted in de088dd3a0, because the initial commit was
reverted.

This commit reverts both the reverting commits, 7a443b1c49 and
de088dd3a0.

Original commit message is below.

If llvm-symbolize did not find module, the error looked like:

    LLVMSymbolizer: error reading file: No such file or directory

This message does not follow common practice: LLVMSymbolizer is not an
utility name. Also the message did not not contain the name of missed file.

With this change the error message looks differently:

    llvm-symbolizer: error: 'abc': No such file or directory

This format is closer to messages produced by other utilities and allow
proper coloring.
