xen-tools: Pass -Wno-vla-parameter to workaround when compiling with gcc-11

When compiling xen-tools (4.14 and 4.15) with gcc-11 the following kind of
errors are produced:

linux.c:164:50: error: argument 7 of type 'const xen_pfn_t[]' {aka 'const long unsigned int[]'} declared as an ordinary array [-Werror=vla-parameter]
  164 |                                  const xen_pfn_t arr[/*num*/], int err[/*num*/])
      |                                  ~~~~~~~~~~~~~~~~^~~~~~~~~~~~

Workaround it by passing -Wno-vla-parameter to the compiler.
