t3902: Protect against OS X normalization

84249819: "Fix invalid read in quote_c_style_counted" introduced a test
that used "caractère spécial" as a directory name.

Git creates it as "caract\303\250re sp\303\251cial"
OS X stores it as "caracte\314\200re spe\314\201cial"

To work around this problem, use the already introduced $FN as the
directory name.
