[v2] doc: add examples.dox path to STRIP_FROM_PATH

  examples.dox is built inside builddir/doc/api and so doxygen generates
some dir_HASH.html that includes the builddir name and this may prevent
DPDK documentation to be correctly generated in some distributions, for
example CentOS Stream 9 and RHEL9, since the builddir includes the
architecture.

This commit adds builddir/doc/api (the path where examples.dox is
generated) to STRIP_FROM_PATH, so the generated documentation doesn't
change if builddir changes.

Fixes: a6090630f4e5 ("doc: automate examples file list for API")

v2:
 - Don't use another VARIABLE name, but set STRIP_FROM_PATH with the 2
   paths directly (suggested by David Marchand)
 - Strip the full path of examples.dox (except the last component)
   instead of stripping only build_root. This is needed since doxygen
   generates the HASH of dir_HASH.html filename using the last component
   of the path and so if the last part of buildroot is changed, the
   filename is different.

Applied, thanks.
