Clang 19 complains with the following error when building libxl:
libxl_utils.c:48:15: error: variable length array folded to constant array as an extension [-Werror,-Wgnu-folding-constant]
48 | char path[strlen("/local/domain") + 12];
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
Replace the usage of strlen() with sizeof, which allows the literal
string length to be known at build time. Note sizeof accounts for the
NUL terminator while strlen() didn't, hence subtract 1 from the total
size calculation.
