avxjudge: adjust regex for matching function names

Golang binaries have been observed to contain function names with many
other ASCII characters not captured by the previous regex.

Adjust that regex by permitting arbitrary characters for the function
name component of the line (between the ` <` and `>:`) and declaring the
expected content for the rest of the line.
