[compiler-rt][asan] Fix incorrect regexp breaking an asan unittest on win64

On windows, the memcpy and memmove function can be the same.
This is correcly detected when hooking, but it's not possible
to report the right function name when doing symbolisation.

The same fix was applied for the static asan unittest.
We forgot to apply the fix for the dynamic asan tests.
lvm\projects\compiler-rt\test\asan/TestCases/Windows/.svn/text-base/intercept_memcpy.cc.svn-base:// CHECK-NEXT:  __asan_{{.*}}mem{{.*}}

This patch is fixing this test (win64):
ddressSanitizer-x86_64-windows-dynamic :: TestCases/Windows/dll_intercept_memcpy_indirect.cc
