 Hadrian: ability to run a subset of the testsuite

 This was supposed to be working already but didn't work when we
 specified several tests with --only. This patch not only fixes this
 but also makes it possible to specify a subset of tests to run with the
 TEST environment variable, like the make build system. Here are some
 examples:

     hadrian/build.sh test --only=plugins01
     hadrian/build.sh test --only="plugins01 plugins02"
     TEST="plugins01 plugins02" hadrian/build.sh test
     TEST=plugins03 hadrian/build.sh test --only="plugins01 plugins02"

 When both the TEST environment variable and the --only flag are used,
 we simply concatenate the list of tests from both sources and ask the
 testsuite driver to run them all.

 This patch addresses #16026.

 Test Plan: hadrian/build.sh test --only="plugins01 plugins02"
