examples/mfem: scale test problem size down to <2000 dofs

This is to speed up the test suite, especially with slower backends
like Occa is at the moment. Larger problem sizes aren't necessary for
correctness testing, but performance regression testing may be
introduced at a later time.

Makefile: use pattern rule for MAGMA's multiple targets

Non-pattern rules do not support multiple targets built by a single
recipe. Instead, they mean that each target can be built by running
the recipe multiple times (the recipe has different $@ each time it is
run). This is noisy and especially a problem with parallel make where
simultaneous invocations could collide.

Make: use CURDIR in pattern rules to match generated *.d absolute paths

This is benign for normal files because stat doesn't care if the path
is relative or absolute, but if the *.c or *.cu source file is
generated, then it matters whether they match or not. Specifically,
it can cause a pattern rule to either not match or to match
twice (once as a relative path via explicit prerequisite in the
makefile and again via the *.d depending on abspath).
