configure.ac: fix sed failure on FreeBSD

Simplify the sed expression to make sure it works on all platforms.

The previous expression failed on FreeBSD and it caused the SNMP_LIBS
variable to be empty. When SNMP_LIBS is empty it will cause binaries
and/or libraries to not link against the correct libraries.
