systemd: enforce en_US.UTF-8 locale in systemd units

Python code does detection of the system encoding based on the locale
settings. On RHEL 8.4 development images we somehow get LANG=en_US which
defaults to iso8859-1 _inside_ the systemd-started service, even though
the whole environment defaults to LANG=en_US.UTF-8.

When instrumented with ExecStartPre=/usr/bin/locale, the following
output can be seen:

locale[45481]: LANG=en_US
locale[45481]: LC_CTYPE="en_US"
locale[45481]: LC_NUMERIC="en_US"
locale[45481]: LC_TIME="en_US"
locale[45481]: LC_COLLATE="en_US"
locale[45481]: LC_MONETARY="en_US"
locale[45481]: LC_MESSAGES="en_US"
locale[45481]: LC_PAPER="en_US"
locale[45481]: LC_NAME="en_US"
locale[45481]: LC_ADDRESS="en_US"
locale[45481]: LC_TELEPHONE="en_US"
locale[45481]: LC_MEASUREMENT="en_US"
locale[45481]: LC_IDENTIFICATION="en_US"
locale[45481]: LC_ALL=
ipactl[45483]: Unexpected error
ipactl[45483]: SystemEncodingError: System encoding must be UTF-8, 'iso8859-1' is not supported. Set LC_ALL="C.UTF-8", or LC_ALL="" and LC_CTYPE="C.UTF-8".
systemd[1]: ipa.service: Main process exited, code=exited, status=1/FAILURE

Set the environment to explicit LC_ALL=C.UTF-8 to please the Python
code. FreeIPA server side only cares about actual encoding, not the
language itself. We already use LC_ALL=C.UTF-8 in httpd service snippet.
