Tianon Gravi bb2c469018 Convert explicit "export A=B" lines of Apache's envvars file into "${A:=B}" such that we can override them at runtime easily
Before:

```sh
unset HOME

if [ "${APACHE_CONFDIR##/etc/apache2-}" != "${APACHE_CONFDIR}" ] ; then
	SUFFIX="-${APACHE_CONFDIR##/etc/apache2-}"
else
	SUFFIX=
fi

export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data
export APACHE_PID_FILE=/var/run/apache2/apache2$SUFFIX.pid
export APACHE_RUN_DIR=/var/run/apache2$SUFFIX
export APACHE_LOCK_DIR=/var/lock/apache2$SUFFIX
export APACHE_LOG_DIR=/var/log/apache2$SUFFIX

export LANG=C

export LANG
```

After:

```sh
unset HOME

if [ "${APACHE_CONFDIR##/etc/apache2-}" != "${APACHE_CONFDIR}" ] ; then
	SUFFIX="-${APACHE_CONFDIR##/etc/apache2-}"
else
	SUFFIX=
fi

: ${APACHE_RUN_USER:=www-data}
export APACHE_RUN_USER
: ${APACHE_RUN_GROUP:=www-data}
export APACHE_RUN_GROUP
: ${APACHE_PID_FILE:=/var/run/apache2/apache2$SUFFIX.pid}
export APACHE_PID_FILE
: ${APACHE_RUN_DIR:=/var/run/apache2$SUFFIX}
export APACHE_RUN_DIR
: ${APACHE_LOCK_DIR:=/var/lock/apache2$SUFFIX}
export APACHE_LOCK_DIR
: ${APACHE_LOG_DIR:=/var/log/apache2$SUFFIX}
export APACHE_LOG_DIR

: ${LANG:=C}
export LANG

export LANG
```
