  [lldb] Add more dylib paths for exception breakpoints

When setting a breakpoint upon throwing exceptions, LLDB only
searches for the libc++abi code inside dylibs named:
  1. libc++abi.dylib
  2. libSystem.B.dylib

However, this fails to account for libs with a version number. For
example, when building the libcxx and libcxxabi runtimes, the following
dylibs are generated:

build/lib/libc++abi.1.0.dylib
build/lib/libc++abi.1.dylib -> libc++abi.1.0.dylib
build/lib/libc++abi.dylib -> libc++abi.1.dylib

If we are debugging a program linked against any of the "versioned"
libs, the breakpoint doesn't work. This commit adds these names to the
search list.
