Switch -e (enumerate host tests) doesn't supoprt 'yotta test'

[PrzemekWirkus]

Currently yotta test command executes in module subdirectory and mbedgt (greentea) can't deduce and enumerate host tests in default module/test/host_tests.

How to reproduce:

$ cd C:\Work\mbed-drivers
$ yotta test

• yotat test execution directory of tests (mbedgt): c:\Work\mbed-drivers\build\frdm-k64f-gcc\test
  • Default host test directory assumed by greentea: c:\Work\mbed-drivers\build\frdm-k64f-gcc\test\test\host_tests
  • Should be: c:\Work\mbed-drivers\build\test\host_tests
