compat: add missing #include <sys/resource.h>

Starting with commit c793430 (Limit file descriptors used by packs,
2011-02-28), git uses getrlimit to tell how many file descriptors it
can use.  Unfortunately it does not include the header declaring that
function, resulting in compilation errors:

 sha1_file.c: In function 'open_packed_git_1':
 sha1_file.c:718: error: storage size of 'lim' isn't known
 sha1_file.c:721: warning: implicit declaration of function 'getrlimit'
 sha1_file.c:721: error: 'RLIMIT_NOFILE' undeclared (first use in this function)
 sha1_file.c:718: warning: unused variable 'lim'

The standard header to include for this is <sys/resource.h> (which on
some systems itself requires declarations from <sys/types.h> or
<sys/time.h>).  Probably the problem was missed until now because in
current glibc sys/resource.h happens to be included by sys/wait.h.

MinGW does not provide sys/resource.h (and compat/mingw takes care of
providing getrlimit some other way), so add the missing #include to
the "#ifndef __MINGW32__" block in git-compat-util.h.
