[musl] [PATCH] Update __procfdname and seed48 proto to conform to header

["Élie Brami" <elie.brami@epita.fr>]

In new GCC11 when -Werror=array-parameter=1 is added we get some mismatch

src/internal/procfdname.c:3:25: error: argument 1 of type 'char *' declared as a pointer [-Werror=array-parameter=]
    3 | void __procfdname(char *buf, unsigned fd)
