fetch test: avoid use of "VAR= cmd" with a shell function
Just like assigning a nonempty value, assigning an empty value to a
shell variable when calling a function produces non-portable behavior:
in some shells, the assignment lasts for the duration of the function
invocation, and in others, it persists after the function returns.
Use an explicit subshell with the envvar exported to make the behavior
consistent across shells and crystal clear.
All previous instances of this pattern used "VAR=value" (with nonempty
`value`), which is already diagnosed automatically by "make test-lint"
since a0a630192d (t/check-non-portable-shell: detect "FOO=bar
shell_func", 2018-07-13).
Noticed using an improved "make test-lint".
