Skip ldd check on ARM Linux (#625)

While the commonly used glibc hack-patch enables kodi on ARM Linux
to use the ChromeOS widevine library ldd will still correctly
fail with an error message because of the missing GLIBC_ABI_DT_RELR
dependency.

This makes the test quite useless on ARM, results in repeated
logspam and the logged error may also be misleading to users.
