description:
Even though msdosfs never truncates file names it advertises _PC_NO_TRUNC
as zero.  Make it advertise one (no_trunc == true).

Names longer than NAME_MAX (255) will never pass namei() btw.

Fixes PR #43670 (msdosfs claims support for filenames longer than {NAME_MAX},
                 but fails)
