Remove static keyword from vshReadline when readline does not exist
Remove static keyword from vshReadline when readline does not exist

This patch removes the static keyword from the vshReadline which was
introduced in commit 834c5720e4434f0bcc807bb1cf20855af63e24a3. With
readline the vshReadline function is not static but when compiling
without readline it was defined as static which caused compilation
error.
