[Qemu-trivial] [PATCH 1/5] configure: remove duplicate single quotes on config.log header

[Cleber Rosa]

The generation of the informational header on config.log contains two
pairs of single quotes, which seems unintentional, and looks like
this:

  # QEMU configure log Thu Jul 26 08:17:15 EDT 2017
  # Configured with: './configure' '--target-list=x86_64-softmmu'

With this change, the quotes comprehend the entire command line:

  # QEMU configure log Mon Jul 26 08:17:35 EDT 2017
  # Configured with: './configure --target-list=x86_64-softmmu'
