Add linux-64 patch for mavros GeographicLib CONFIG mode

[TayebAlsh]

Summary

• Adds patch to fix mavros build on linux-64 platform
• Changes find_package(GeographicLib REQUIRED) to find_package(GeographicLib REQUIRED CONFIG) to use the conda package's cmake config instead of the system FindGeographicLib.cmake module

Packages enabled for linux-64

• ros-humble-mavlink
• ros-humble-libmavconn
• ros-humble-mavros-msgs
• ros-humble-mavros

Test plan

• Built locally with pixi run build
• All packages compiled successfully
• All tests passed

Notes

The mavlink, libmavconn, and mavros-msgs packages build without patches. Only mavros required this patch due to GeographicLib detection using the system cmake module instead of the conda-forge package's config.
