Description: Fix GCC-10 ftbfs when used with -Werror=format-overflow=
Process names have a maximum length of 16 bytes and the buffer used has a
length of 16 bytes, but the compiler is picky about writing and arbirary
string into that small buffer. Tell the compiler to write max. 15 chars +
'\0', to make it happy.
