driconfig: add a new engine name/version parameter

Vulkan applications can register with the following structure :

typedef struct VkApplicationInfo {
    VkStructureType    sType;
    const void*        pNext;
    const char*        pApplicationName;
    uint32_t           applicationVersion;
    const char*        pEngineName;
    uint32_t           engineVersion;
    uint32_t           apiVersion;
} VkApplicationInfo;

This enables the Vulkan implementations to apply workarounds based off
matching this description.

Here we add a new parameter for matching the driconfig options with
the following :

    <device driver="anv">
        <application engine_name_match="MyOwnEngine.*" engine_versions="10:12,40:42">
            <option name="blaaah" value="true" />
        </application>
    </device>

v2: switch engine name match to use regexps

v3: Verify that the regexec returns REG_NOMATCH for match failure (Eric)

v4: Add missing bit that went to the following commit (Eric)
