profile_tool.py: Fix traceback in sub command

[yuumasato]

Description:

• Fix traceback when diffing ocp4 profiles.

$ build-scripts/profile_tool.py sub --build-config-yaml ./build/build_config.yml --ssg-root ./ --product ocp4 --profile2 products/ocp4/profiles/high-rev-4.profile --profile1 products/ocp4/profiles/moderate.profile

During handling of the above exception, another exception occurred:

RuntimeError: Error loading a Profile from products/ocp4/profiles/moderate.profile: 'NoneType' object has no attribute 'get_cpe_name'

Rationale:

• I don't know why the tool doesn't segfault when diffing rhel8 or rhel9 profiles
• This tool is pretty handy to compare rule selection differences in profiles.
  • It can compare source profile files and compiled(rendered) profile files.

Review Hints:

• Build the content (./build/build_config.yml needs to be generated)
  • e.g: $ ./build_product ocp4
• Diff two profiles:

$ build-scripts/profile_tool.py sub --build-config-yaml ./build/build_config.yml --ssg-root ./ --product ocp4 --profile2 products/ocp4/profiles/high-rev-4.profile --profile1 products/ocp4/profiles/moderate.profile
Subtraction would produce an empty profile. No new profile was generated

$ build-scripts/profile_tool.py sub --build-config-yaml ./build/build_config.yml --ssg-root ./ --product ocp4 --profile2 products/ocp4/profiles/high-rev-4.profile --profile1 products/ocp4/profiles/e8.profile
12 rules were left after subtraction.
0 variables were left after subtraction.
Creating a new profile containing the exclusive selections: e8_sub_high-rev-4.profile
Profile e8_sub_high-rev-4.profile was created successfully

When control files are used it makes more sense to compare compiled profile files:

$ build-scripts/profile_tool.py sub --build-config-yaml ./build/build_config.yml --ssg-root ./ --product ocp4 --profile1 build/ocp4/profiles/high-rev-4.profile --profile2 build/ocp4/profiles/e8.profile
122 rules were left after subtraction.
3 variables were left after subtraction.
Creating a new profile containing the exclusive selections: high-rev-4_sub_e8.profile
Profile high-rev-4_sub_e8.profile was created successfully

I have run the review hints and also I have tried to run the tool on RHEL 9 profiles.
