stdin_is_not_tty is detected too late when the --help message is
printed, so fix this and do not call ioctl if stdin is not tty.
Before this patch:
$ clickhouse-client --help < /dev/null
debug build:
$ dbms/programs/clickhouse-client --help < /dev/null
Main options:
--help
clickhouse-client: ../contrib/boost/libs/program_options/src/options_description.cpp:542:
void boost::program_options::{anonymous}::format_description(std::ostream&, const string&, unsigned int, unsigned int): Assertion `line_length > first_column_width' failed.
Aborted (core dumped)
release build:
$ dbms/programs/clickhouse-client --help < /dev/null
.... print lots of empty lines and so forth ...
v2: add a test and bsdutils into image for tests
v3: adjust minimal cols to the length of one of the longest arguments,
since with line_length=3 boost will bail anyway (under script(1)
ioctl(TIOCGWINSZ) returnes ws_col=0)
