Hishtory: Add to package lists and fix setup script

Add hishtory to both darwin and linux package lists with eget options
for its non-standard release assets (bare binaries, no archives).

Rework the setup script to use install --skip-config-modification
instead of init, so that config.{sh,zsh} shell integration files are
created. Use a temp copy workaround for a hishtory bug where install
unlinks the binary on PATH before copying os.Args[0] to it, which
fails when they are the same file. Set HISHTORY_SERVER during install
so the host registers with the custom sync server.

+# We use `hishtory install --skip-config-modification` rather than `hishtory init`

+# --skip-config-modification prevents install from mangling shell rc files, since

+# The temp copy workaround is needed because install does the following:

+# temp copy ensures the source survives the unlink.
