gst1-plugins-base: remove legacy freetype handling

In 2010 commit 32d319e6f "gst-plugins-base: ensure <stdint.h> is used"
introduced a typo (missing backslash) that made the code ineffective.

In 2013 commit f8e7fdcd3 "gst1-plugins-base: add gstreamer1 base
plugins" copied the code.

It can be confirmed by looking at the output of:
$ make printvars | grep '^GST1_PLUGINS_BASE_CONF_ENV\|^FT2_CONFIG'
FT2_CONFIG=/bin/false ac_cv_header_stdint_t="stdint.h"
GST1_PLUGINS_BASE_CONF_ENV=

Direct use of freetype was dropped in version 1.7.2 by upstream [1], so
remove the code instead of fixing it.

Found using [2]:
check-package --include-only Indent $(find * -type f)
and manually removed.
