[Qemu-devel] [PULL 07/15] archive-source.sh: Modern shell scripting (use $() instead of ``)

[Thomas Huth <thuth@redhat.com>]

From: Mao Zhongyi <maozhongyi@cmss.chinamobile.com>

Various shell files contain a mix between obsolete ``
and modern $(); It would be nice to convert to using $()
everywhere.
