Fix ironic-python-agent - CA bundle inject

Currently the pxe-init script copies the certificate bundle directly
to /etc/pki/ca-trust/extracted in the initramfs. When update-ca-trust
runs under chroot the contents under pki/ca-trust/extracted is
overwritten. See manual page: update-ca-trust(8) "EXTRACTED
CONFIGURATION" section.

With this change the bundle is copied to /etc/pki/ca-trust/source/anchors
directory in the initramfs instead, so that update-ca-trust will find the
source and update CA certs and trusts correctly.
