Remove custom gphoto2 install

[wtgee]

This pull request includes changes to the scripts/install/install-pocs.sh script to update the installation process by modifying system dependencies and removing redundant installation steps.

Updates to system dependencies and installation steps:

• scripts/install/install-pocs.sh: Added gphoto2 to the list of system dependencies in the system_deps function.
• scripts/install/install-pocs.sh: Removed the install_gphoto2 and write_udev_entries steps from the do_install function, as they are no longer needed. The write_udev_entries will happen as part of pocs mount setup.
