test/filters/namespaces.c: use tabs for indentation

This appears to be the only C file in the repository that uses spaces
for indentation.

Commands used to check for the above:

    $ git grep '^        ' -- '*.c' '*.h'

Commands used to search and replace:

    $ f=test/filters/namespaces.c; printf '%s\n' \
        "$(sed 's/    /\t/g' "$f")" >"$f"

Note: The mmap call was aligned manually.

Added on commit 5116c1ced ("testing", 2022-12-24).
