[symbolizer] Empty string is not an error (#92660)
After commit 1792852f86dc7 ([symbolizer] Change reaction on invalid
input) llvm-symbolizer issues an error on malformed command instead of
echoing it to the standard output, as in previous versions. It turns out
this behavior broke a use case when echoing was used to check if
llvm-symbolizer is working (1792852f86 (commitcomment-142161925)).

With this change an empty line as input is not considered as an error
anymore and does not produce any output on stderr. llvm-symbolizer still
respond on empty line with line not found, this is consistent with GNU
addr2line.
