escape.c: Fix missing nl_langinfo on certain configs
With !129 (merged) and this, I am able to build procps on a musl based system.
The issue was that nl_langinfo
and CODESET
were undefined.
This is expected because langinfo.h
was included only on certain conditions.
So I used the nls.h
unconditionally, which provides a fallback if the libc does not support langinfo.h
.
FYI, musl does support langinfo.h
.
