Cherry-pick WebKit change 59226 to use standard POSIX version of writeToFile()

The Android version of writeToFile() tries to support interrupted writes, but
has a bug as the data pointer is not updated. So instead we take the standard
POSIX version.

See https://mondrian.corp.google.com/changelist/75998-p9
and https://bugs.webkit.org/show_bug.cgi?id=38908
