largefiles: handle that a found standin file doesn't exist when removing it

I somehow ended up in a situation where hg crashed on an unlink I introduced in
328545c7d8a1.

I don't know how it happened and can't reproduce it. It seems like it only can
happen when the file is removed between the time of check in a working
directory context walk that finds a standin file, and the time of use when we
try to remove it because the corresponding largefile doesn't exist.

But better safe than sorry: replace the plain unlink with unlinkpath with
ignoremissing=True. That will also remove remaining empty directories, which
arguably is more correct.

from mercurial import (
    util,

def makedate():
    return 0, 0
def getuser():
    return 'bob'
def getpid():
    return 5000

# mock the date and user apis so the output is always the same
def uisetup(ui):
    util.makedate = makedate
    util.getuser = getuser
    util.getpid = getpid
