rhg: ignore readonly FS error when saving dirstate

The error is already ignored when the .hg directory is read-only,
so this is only fair. (the python hg is silent on readonly fs, too)

from mercurial.utils import procutil

# XXX: we should probably offer a devel option to do this in blackbox directly
def getuser():
    return b'bob'


def getpid():
    return 5000


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