testsuite: Don't xfail gcc.dg/debug/dwarf2/inline5.c

gcc.dg/debug/dwarf2/inline5.c has been XPASSing on Solaris (both SPARC
and x86, 32 and 64-bit) with the native assembler since 20210429.
According to gcc-testresults postings, the same is true on AIX.

XPASS: gcc.dg/debug/dwarf2/inline5.c scan-assembler-not \\\\(DIE \\\\(0x([0-9a-f]*)\\\\) DW_TAG_lexical_block\\\\)[^#/!@;\\\\|]*[#/!@;\\\\|]+ +DW_AT.*DW_TAG_lexical_block\\\\)[^#/!@;\\\\|x]*x\\\\1[^#/!@;\\\\|]*[#/!@;\\\\|] +DW_AT_abstract_origin

This is obviously due to

    fix asm-not pattern in dwarf2/inline5.c

This patch thus removes the xfail.

Tested on i386-pc-solaris2.11 (as and gas), sparc-sun-solaris2.11 (as
and gas), and i686-pc-linux-gnu.
