gdb's debuginfod progress messages include the size of the file being
downloaded if the size information is available at the time the message
is printed. For example:
Downloading 10 MB separate debug info for /lib64/libxyz.so
This size information is omitted if it's not available at the time of
printing:
Downloading separate debug info for /lib64/libxyz.so
A pattern in crc_mismatch.exp fails to be matched if a progress message
includes a file size. Add a wildcard to the pattern so that it matches
the progress message whether or not it includes the file size.
