This commit allows cc_prebuilt version suffix to include `svn`, e.g.
`libclang.so.8svn`. The rationale behind this commit is that latest
LLVM/Clang prebuilt binaries use `.8svn` as the version suffix.

This commit changes how `cc/androidmk.go` generates LOCAL_MODULE_STEM,
LOCAL_MODULE_SUFFIX, and LOCAL_BUILT_MODULE_STEM. Now, `splitFileExt()`
takes a file name and a list of expected file extensions.
`splitFileExt()` searches the first occurrence of expected file
extensions in the file name. If it can not find any, it will simply
return the last file extension.
Before this commit, `cc/androidmk.go` simply extracts the last file
extension (e.g. `.so`). However, if the prebuilt shared libs end with
version numbers (e.g. `libc++.so.1`), it will use `$(LOCAL_MODULE).1` as
LOCAL_BUILT_MODULE_STEM and this will lead to missing target ninja
error.

Test: Build a program that links libc++_host (from prebuilts/clang)
