[testsuite] Clear hardware capabilities for gcc.dg/vect/vect-simd-clone-*.c

The new gcc.dg/vect/vect-simd-clone-*.c tests were FAILing on Solaris
10+/x86 with Sun as:

FAIL: gcc.dg/vect/vect-simd-clone-1.c execution test

ld.so.1: vect-simd-clone-1.exe: fatal: vect-simd-clone-1.exe: hardware capability (CA_SUNW_HW_2) unsupported: 0x40  [ 0x40 ]

As can be seen in <sys/auxv_386.h>, this is:

#define AV2_386_AVX2            0x00040 /* Intel AVX2 insns */

Since the tests check for avx2 support at runtime, we need the same
solution as in gcc.target/i386: clear the hardware capabilities when
linking the executable.

Tested on i386-pc-solaris2.10 and x86_64-unknown-linux-gnu, installed on
mainline.

	* gcc.dg/vect/vect.exp: Add clearcap_ldflags to DEFAULT_VECTCFLAGS
	if supported.
