configure: show pkg names when libkeyutils is missing

Prior to this commit, when ./configure can't find libkeyutils, it would
bail out with a terse error message.

Some of the other library checks helpfully print the DEB and RPM package
names in parentheses. Add the DEB and RPM package names to the
libkeyutils check.
