meta-security: fix incorrect HOMEPAGE variable names

Several recipes used non-standard variable names for the homepage
URL (HOME_PAGE, HOME_URL, HOMEDIR) which are not recognized by
bitbake. Rename them all to the correct HOMEPAGE variable.

Affected recipes:
- glome: HOME_PAGE -> HOMEPAGE
- google-authenticator-libpam: HOME_PAGE -> HOMEPAGE
- arpwatch: HOME_PAGE -> HOMEPAGE
- openscap: HOME_URL -> HOMEPAGE
- scap-security-guide: HOME_URL -> HOMEPAGE
- lynis: HOMEDIR -> HOMEPAGE
