Catch more generic FileSystemException in NamedPipeSocket (#1418)

bsideup · web-flow · commit 54c86cee58e8 · 2020-06-19T14:10:09.000+02:00
When npipe is busy, it throws the following exception:
`java.nio.file.FileSystemException: \\.\pipe\docker_engine: All pipe instances are busy.`

The previous, RandomAccessFile-base implementation was catching it as `FileNotFoundException`.
But the NIO-based one seems to be throwing a generic `FileSystemException`.
