ignore write errors to pack children while closing a repository

If the child has exited for some reason then we won't be able to send a
stop message on the pipe. Ignore such errors while we are tearing a repository
data structure down. The error should be harmless but can trip up gotwebd
when cycling repositories out of its repo cache:
gotwebd[29683]: gotweb_render_index: got-portable.git: unexpected end of file
