icasefs: use case preserved root for 'util.fspath()' invocation (issue3302)

path to repo root may contains case sensitive part, even though repo
is located in case insensitive filesystem: e.g. repo in FAT32 device
mounted on Unix.

so, case normalized root causes failure of stat(2).

this patch uses case preserved root for 'util.fspath()' invocation to
avoid this problem.

case preserved root for 'util.fspath()' may decrease efficiency of
fspath cache, but 'util.fspath()' is currently called only from
dirstate, so this fix has less impact.
