[PATCH ima-evm-utils] Include sys/types.h in header to fix build with musl

[luca.boccassi@xxxxxxxxx]

From: Luca Boccassi <luca.boccassi@xxxxxxxxxxxxx>

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.
