build--pkglist: remove --full
build--pkglist: remove --full

This was introduced in 27573513d890f37a9c064bbd3e9431bade5b0987 to aid
with the --dry-run flag (commit
177a17988093b86ca44b99aa3cef24efe378a9b8). Since this flag was removed
again, there is no direct use for aur-build--pkglist --full either.
