Fix bug #81598: Use C.UTF-8 as LC_CTYPE locale by default

Unfortunately, libedit is locale based and does not accept UTF-8
input when the C locale is used. This patch switches the default
locale to C.UTF-8 instead (if it is available). This makes libedit
work and I believe it shouldn't affect behavior of single-byte
locale-dependent functions that PHP otherwise uses.

Closes GH-7635.

Do not inherit LC_CTYPE locale from environment

Treatment of locales in PHP is currently inconsistent: The LC_ALL
locale is set to "C", as is standard behavior on program startup.
The LC_CTYPE locale is set to "", which will inherit it from the
environment. However, the inherited LC_CTYPE locale will only be
used in some cases, while in other cases it is necessary to perform
an explicit setlocale() call in PHP first. This is the case for
the locale-sensitive handling in the PCRE extension.

Make things consistent by *never* inheriting any locales from the
environment. LC_ALL, including LC_CTYPE will be "C" on startup.
A locale can be set or inherited through an explicit setlocale()
call, at which point the behavior will be fully consistent and
predictable.

Closes GH-5488.
