Find matching variant of `required` for `common_first`

Both 32-bit and 64-bit variants of native deps were getting installed in
Soong-built system image if they were listed in `required` of
`java_binary`.

java_binary(s) have two variants, a "common" and an arch
variant (the first arch). Previously the common variant will create a
dependency to both 32-bit and 64-bit variants of their dependencies.
With this CL, common variant will not create a dependency on required
unless the requested `target` is also the common target.

Test: Ran the filelistdiff tool
Test: go test ./java -run TestNativeRequiredDepOfJavaBinary
