    qemu: Add pkg-config handling for libgcrypt
    
    When PACKAGECONFIG libgcrypt is enabled, we would get the following error.
    
    ERROR: /usr/bin/libgcrypt-config should not be used, use an alternative such as pkg-config
    
    In oe-core, libgcrypt has been turned to be configured with pkg-config instead
    of libgcrypt-config, but qemu configure script does not contain pkg-config
    related part for libgcrypt to handle it.
