buildgcc: Match the string of downloading percentage more precisely

The command "wget" prints some hyperlink with "%", which will be
filtered in by previous regular expression. So we need to change to
match the string with exactly 3 digits and a percent symbol.

TEST:
echo 45%  | grep -o "\<[0-9]\{1,3\}%"
  45%
echo 1245% | grep -o "\<[0-9]\{1,3\}%"
  <empty>
echo aa%  | grep -o "\<[0-9]\{1,3\}%"
  <empty>
