Remove `partitioning_mode = "raw"` customization in blueprints once OpenSCAP is updated to add it

[matusmarhefka]

It was added in #586 and the following part of code can be removed once OpenSCAP/openscap#2334 is resolved:

contest/lib/osbuild.py

Lines 390 to 420 in 183e64c

	# Partitioning mode defaults to auto-lvm which uses lvm because we use
	# filesystem customizations in blueprints; root LV then stays near the
	# 1 GiB / + 2 GiB /usr hard-coded minimum size with free space left in the VG.
	# Switch to raw layout which grows the / partition to fill the disk, see
	# https://osbuild.org/docs/user-guide/partitioning/
	# https://osbuild.org/docs/user-guide/blueprint-reference/#partitioning-mode
	bp_new = re.sub(
	r'^partitioning_mode\s*=\s*"[^"]*"\s*$',
	'partitioning_mode = "raw"',
	bp_text,
	count=1,
	flags=re.M,
	)
	if bp_new != bp_text:
	bp_text = bp_new
	elif not re.search(r'^partitioning_mode\s*=\s*"raw"\s*$', bp_text, flags=re.M):
	bp_text, inserted = re.subn(
	r'^(\[customizations\]\s*\n)',
	r'\1partitioning_mode = "raw"\n',
	bp_text,
	count=1,
	flags=re.M,
	)
	if not inserted:
	bp_text = re.sub(
	r'^(version = .*\n)',
	r'\1\n[customizations]\npartitioning_mode = "raw"\n',
	bp_text,
	count=1,
	flags=re.M,
	)
