isofs: report the Joliet name length in statfs
isofs_statfs() reports NAME_MAX as the longest name, but a Joliet name
can now be up to JOLIET_NAME_MAX bytes long. glibc answers
pathconf(_PC_NAME_MAX) from f_namelen, so a program sizing a buffer from
it should get room for every name readdir returns. vfat has reported
255 times NLS_MAX_CHARSET_SIZE, 1530, since commit f68e542f3478 ("fat:
Fix statfs->f_namelen"), which followed a report of readdir_r()
overflowing a buffer sized that way, and exfat reports the same.
Windows reports a maximum component length of 110 for CDFS.
Report JOLIET_NAME_MAX on Joliet mounts. Rock Ridge and plain ISO 9660
mounts keep NAME_MAX.
