depends: libXext isn't needed by anyone

libXext was only needed (as a library) by QT when it was using
XLib/libX11 (as a library), now that we're building QT without
XLib/libX11, we can safely remove libXext.

-  # A number of steps in the autoconfig process implicitly assume that the build

-  # work around these issues, the --enable-malloc0returnsnull (or
-  # --disable-malloc0returnsnull, depending on the host system) must be passed

-  # Concretely, between the releases of libXext 1.3.2 and 1.3.3,
-  # XORG_CHECK_MALLOC_ZERO from xorg-macros was changed to use the autoconf
-  # cache, expecting cross-compilation environments to seed this cache as there
-  # is no single correct value when cross compiling (think uclibc, musl, etc.).
-  # You can see the actual change in commit 72fdc868b56fe2b7bdc9a69872651baeca72
-  # in the freedesktop/xorg-macros repo.
-  #
-  # As a result of this change, if we don't seed the cache and we don't use
-  # either --{en,dis}able-malloc0returnsnull, the AC_RUN_IFELSE block has no
-  # optional action-if-cross-compiling argument and configure prints an error
-  # message and exits as documented in the autoconf manual. Prior to this
-  # commit, the AC_RUN_IFELSE block had an action-if-cross-compiling argument
-  # which set the more pessimistic default value MALLOC_ZERO_RETURNS_NULL=yes.
-  # This is why the flag was not required prior to libXext 1.3.3.
