Remove redundant URI path segment check in parse_request

[eugenepaniot]

This commit proposes the removal of a redundant URI path segment check within the parse_request function.

Currently, the code contains a loop that iterates over each path segment in the parsed URI, checking for the presence of . or .. segments. However, this check is unnecessary since HTTP requests with /./ or /../ in the URI are automatically corrected by the http server, converting them into // which is the expected behavior.

The primary reason for removing this check is to address an issue detailed in the GitHub pull request https://github.com/tarantool/http/pull/173. In cases where Tarantool decodes a request like .%2F.html.%2F to ./.html./, the current code implementation throws an invalid uri error. However, this behavior is not desired. Instead, it is expected to return the URI as is.
