[Qemu-devel] [PATCH 1/4] update get_file_size to not throw error on non-existant files

[Ryan Harper <ryanh@us.ibm.com>]

In some cases, when qemu is just starting up the logfile hasn't yet
been created and will throw an error message into the output:

ls: cannot access .tmp-3070/logfile-3070.log: No such file or directory

if we check to see if the file is readable first then we know the file
is present and we can extract the size.
