Ethereal-dev: [Ethereal-dev] Minor fix to autoconf test for net-snmp

Note: This archive is from the project's previous web site, ethereal.com. This list is no longer active.

While the test for net-snmp is correct, the test output is incorrect.
The AC_MSG_CHECKING text will appear on a line with no newline. Then
AC_CHECK_HEADERS comes along and spits out text on the *same* line.
Then the AC_MSG_RESULT's come on a line different from the
AC_MSG_CHECKING text, which is confusing. I've corrected this below.

Against 0.9.14.
