epiphany/gas: Remove .l suffix from expected test results

In commit 02a79b89fdeadccb67048291e6c2a1e5ce6ad623 all instruction
aliases that have a '.l' suffix were marked as NO-DIS, so the
disassembler will not display them, in preference to the instruction
without the suffix.  However, the gas testsuite was not updated at the
time, this commit fixes that oversight.

gas/ChangeLog:

	* testsuite/gas/epiphany/addr-syntax.d: Remove unneeded '.l'
	suffixes from instruction mnemonics in expected output.
	* testsuite/gas/epiphany/allinsn.d: Likewise.
	* testsuite/gas/epiphany/regression.d: Likewise.
	* testsuite/gas/epiphany/sample.d: Likewise.
