phosphor: net-snmp: clean up configure options

Remove a number of configure option overrides to reduce maintainence
burden.

Remove disable-manuals because the base recipe already does that.

The disable-embedded-perl and disable-perl-cc-checks options are
unnecessary because the perl PACKAGECONFIG is not enabled by default in
the base recipe.

Remove disable-libtool-lock.  The configure script has this to say
about this option:

  avoid locking (might break parallel builds)

bitbake builds with make -j so it seems like a good idea to stick with
the default, and build with libtool locking enabled.  This option has
no runtime effect.

Remove disable-deprecated.  This option is unused by net-snmp.  Just
use the default to minimize the maintainence delta.  It has no runtime
effect.

Remove disable-privacy.  Encryption isn't used at the moment but the
footprint impact on libnetsnmp to leave it at the default (enabled)
is negligible ( < ~10K stripped, uncompressed ).

Remove disable-set-support and disable-snmptrapd-subagent.  These are
agent functions which are currently unused.  Leave at the default.

Remove disable-scripts.  This does grow the client package but the
client package is not used at the moment.  Leave at the default.
