illumos gate

From the python 3.8 "What's new" document:

The following functions and methods are deprecated in the gettext module: lgettext(), ldgettext(), lngettext() and ldngettext(). They return encoded bytes, and it’s possible that you will get unexpected Unicode-related exceptions if there are encoding problems with the translated strings. It’s much better to use alternatives which return Unicode strings in Python 3. These functions have been broken for a long time.

Function bind_textdomain_codeset(), methods output_charset() and set_output_charset(), and the codeset parameter of functions translation() and install() are also deprecated, since they are only used for the l*gettext() functions.

It appears it was always a nop to pass codeset to gettext.install() and so we should be able to just safely remove this and have the resulting program work on all python versions, including 3.11

I've done two illumos-gate builds with the patch in the associated gerrit review:

export BUILDPY2='#'
export BUILDPY3=
export BUILDPY2TOOLS='#'
export BUILDPY3TOOLS=
export PYTHON3_VERSION=3.10
export PYTHON3_PKGVERS=-310
export PYTHON3_SUFFIX=
export TOOLS_PYTHON=/usr/bin/python$PYTHON3_VERSION

and

export BUILDPY2='#'
export BUILDPY3=
export BUILDPY2TOOLS='#'
export BUILDPY3TOOLS=
export PYTHON3_VERSION=3.11
export PYTHON3_PKGVERS=-311
export PYTHON3_SUFFIX=
export TOOLS_PYTHON=/usr/bin/python$PYTHON3_VERSION

Both were successful.
