python3-pyruvate: Fix build with mips

mips/glibc systems have interesting problem where dev_t is not defined
properly for O32 ABI [1], therefore address it for libsystemd crate, it
works fine for musl

Fixes
error[E0308]: mismatched types

+Subject: [PATCH] check for mips targets for stat.st_dev definitions
+
+st_dev has wrong type in glibc when using mips/O32 ABI
+its type should be dev_t but it is set to unsigned long int
+this is specific issue on mips/o32 ABI in glibc for details
+
+See
+https://sourceware.org/bugzilla/show_bug.cgi?id=17786
+
+currently the build fails on mips archirecture with type mismatches
