Systemic fix: all local recipes (~150 references across 40+ Cargo.toml files)
now resolve libredox, redox_syscall, and redox-scheme through
recipes/core/base/ symlinks instead of local/sources/ paths.
Eliminates lockfile collision between Cargo's resolution of the same
package through different path strings (local/sources/ vs recipes/core/base/).
This is required because the base recipe's workspace Cargo.toml resolves
these deps through recipes/core/base/ (via symlink chain from the
recipe copy location), and Cargo treats different path strings to the
same directory as different packages.
