packagegroup-ni-runmode: add aide to runmode RDEPENDS

[Vairamani-NI]

Summary of Changes

Include the AIDE file integrity checker in the runmode packagegroup so it is baked into the base system image (BSI) on device.

Justification

https://dev.azure.com/ni/DevCentral/_workitems/edit/3470293

Testing

Build

• nilrt-base-system-image builds for x64 with the AIDE change; no new build/QA warnings attributable to AIDE.
• ARM (xilinx-zynq): pending — not yet built.
• aide 0.19.3 + aide-lic appear in the nilrt-runmode-rootfs manifest.
• /etc/aide.conf ships the NI policy (verified overrides the upstream sample); /var/lib/aide present.

On-target validation (x64, cRIO-9045, run mode)

• Installed BSI, booted into run mode, aide 0.19.3 functional.
• no false positives: aide --init baseline (33,069 entries), then aide --check on the unmodified image → "AIDE found NO differences … Looks okay!!" (exit 0).
• intrusion detected: modified 1 monitored file, removed 1, added 1 → detected 1 changed / 1 removed / 1 added with per-file hash/size detail (exit 7).

Footprint

• AIDE ~290 KiB installed (/usr/bin/aide 253 KiB + aide-lic 35 KiB); deps already in base.
• Baseline DB aide.db.gz ≈ 2.97 MiB (~33k entries); peak RSS ~45 MiB (--init) / ~59 MiB (--check).

Procedure

• I certify that the contents of this pull request complies with the Developer Certificate of Origin.

Pull request overview

Adds the AIDE file integrity checker to the NI run mode packagegroup so it is included by default in run mode images (and therefore in the base system image composition when this packagegroup is used).

Changes:

• Add aide to packagegroup-ni-runmode RDEPENDS so it is installed in run mode rootfs images.
