Make PKG_CHECK_MODULES report the module name instead of the variable prefix

In Autoconf output from PKG_CHECK_MODULES in pkg.m4, the "checking for"
message refers to the first argument of PKG_CHECK_MODULES, the variable
prefix, instead of the second argument, the module being checked for.

This results in strange output (like ALL CAPS module names) in various
packages. And when probing for modules, one can't always use a variable
prefix that matches the module name (since ‘-’ and other characters
aren't allowed in variable names), so the Autoconf output is going to
refer to something odd.

The status output should reference the module name being probed for,
both because it looks nicer and because, when debugging problems, this
references the actual thing being probed for on the system, rather than
an internal implementation detail.
