package/apache: fix apxs destdir prefix

Apache version 2.4.43 introduced a problem in apxs path handling.
In buildroot apxs and config_vars.mk, all the paths are expressed
as absolute so the trick of guessing a destdir path to prefix to all
the others is not needed and produces wrong paths in the form of
destdir + full path.

Fixes:

Rather than reverting an upstream patch that puports to actually support
cross-compilation, can we instead revisit our hack that shoehorns the
absolute patchs to begin  with?
