Build bionic unit tests for musl
Modify bionic unit tests that are built for glibc so that they also
build against musl. They don't all pass though:
With glibc:
2 SLOW TESTS
4 TIMEOUT TESTS
313 FAILED TESTS
YOU HAVE 2 DISABLED TESTS
With musl:
11 SLOW TESTS
11 TIMEOUT TESTS
363 FAILED TESTS
YOU HAVE 2 DISABLED TESTS
Bug: 190084016
Test: m bionic-unit-tests-glibc with musl
Test: atest bionic-unit-tests-static
Test: atest --host bionic-unit-tests-glibc with glibc
