With correct POSIX handling, unquoted empty variables can turn the
expression like
test -n ${fdtfile}
into
test -n
The POSIX handling for single argument `test` evaluates it as true,
so the fallback initialization will be skipped unexpectedly.
Quoting variable expansions in `test` expressions will always result in
correct behavior for empty and non-empty values.
This change was triggered by
commit 8b0619579b ("cmd: test: fix handling of single-argument form of test")
The aim is to have a less fragile codebase that is not dependent on a
quirk of the shell implementation.
Use quoted variable expansions in `test` expressions throughout.
