  Log Message:
  -----------
  [lldb][windows] _wsopen_s does not accept bits other than `_S_IREAD | _S_IWRITE`

When sending file from a Linux host to a Windows remote, Linux host will try to copy the source file's permission bits, which will contain `_S_I?GRP` and `_S_I?OTH` bits. Those bits are rejected by `_wsopen_s`, causing it to return EINVAL.

This patch masks out the rejected bits.
