Third party programs including libimaevm fails to build with musl
due to a missing include in the public header. Add it.
The build with glibc is unaffected. Patch sent upstream.

+Subject: [PATCH] Include sys/types.h in header to fix build with musl
+
+Building a third program that depends on libimaevm with musl fails, as
+the imaevm.h uses uid_t and gid_t without including sys/types.h:
+
+<..>/sysroot/usr/include/imaevm.h:90:2: error: unknown type name 'uid_t'
+  uid_t uid;
+
+Including sys/types.h fixes building with musl and does not affect
+building with glibc.
