Now clickhouse --help/ch --help will print --help for clickhouse-local,
let's use just "clickhouse help" to get help with list of available
tools in clickhouse binary itself.

Components like client/server/... are very generic, and there is no
point in disabling them, since it does not reduce amount of compiled
code a lot anyway (just a few modules for entrypoints, everything else
is already included in the clickhouse binary), and eventually they are
just symlinks to the clickhouse binary.
But there are few, that requires extra libraries, like ODBC bridge or
keeper components (and there is also standalone keeper binary compiled
with musl), those had been kept.
Also add some descriptions for some utils and change exit code to 0 for
--help.

By "without name" I mean either of this:
- without arguments (except for the argv[0])
- or with arguments starts with dash
This should improve usability, and better ad of the clickhouse-local.

cmake/target.cmake defines macros for the supported platforms, this
commit changes predefined system macros to our own macros.
__linux__ --> OS_LINUX
__APPLE__ --> OS_DARWIN
__FreeBSD__ --> OS_FREEBSD
Some environments may really require LD_LIBRARY_PATH (and some other
variables), so rejecting running clickhouse binaries in such envs is a
backward incompatible change.
So instead of rejecting, let's ignore those env variables, i.e. reexec
binaries without them.
Also note, that there is no messages in stderr in case of some of
variables set anymore, since this message may break some scripts.

Official docs:
Some headers from C library were deprecated in C++ and are no longer
welcome in C++ codebases. Some have no effect in C++. For more details
refer to the C++ 14 Standard [depr.c.headers] section. This check
replaces C standard library headers with their C++ alternatives and
removes redundant ones.
